Docker always returns ports in ascending order, so if they aren't
specified like that in the compose, a restart loop would occur. This
patch changes the port maps to be stored in ascending order, based on
an alphabetical sort of the internalStart port (not taking into account
the protocol). This is the same as how Docker returns them, so they will
match, regardless of input form.

Also change the return format of ApplicationManager.getStatus(), which
does not conform to the above.

Up to now, there was a slim but non-zero chance that an image would be downloaded between the call to `@getTarget` inside deviceState
(which gets the target state and creates Service objects using information from available images), and the call to
`@images.getAvailable` in ApplicationManager (which is used to determine whether we should keep waiting for a download or start the
service). If this race condition happened, then the ApplicationManager would infer that a service was ready to be started (because
the image appears as available), but would have incomplete information about the service because the image wasn't available when
the Service object was created. The result would be that the service would be started, and then immediately on the next applyTarget
the ApplicationManager would try to kill it and restart it to update it with the complete information from the image.
This patch changes this behavior by ensuring that all of the additional information about the current state, which includes available images,
is gathered *before* building the current and target states that we compare. This means that if the image is downloaded after the call to getAvailable, the Service might be constructed with all the information about the image, but it won't be started until the next pass, because ApplicationManager will treat it as still downloading.

We also replace a createTableIfNotExists in the migrations with hasTable then createTable, to
avoid a warning message about it being not recommended.

The move from pure CoffeeScript to TypeScript has brought a
few changes to the way transpiling happens. Previously, through
serendipity, the way `startIPAddressUpdate` was called worked
because of the binding convention pre-transpiling.
However, with the move to TypeScript, this has altered and
the assumption that a lack of parentheses would call the
method before supplying a callback into the returned function
is incorrect. The method must be specifically called first.

When updating from old supervisors (<7.0.0), we've been so far using a fake id 1 for serviceId, imageId
and releaseId since these were not available in the old supervisor. This causes problems when the supervisor
tries to report these values to the API. Moreover, the app from the legacy supervisor has an image URL
that doesn't include the content hash - this causes the supervisor to believe the image is not really downloaded
and try to fetch it again.
To fix these issues, we add a request to the API when the supervisor starts up and detects that there's a legacy
app that needs to be normalised. We fetch the appropriate release, and use it to populate the resource ids
and the updated image URL.
This should avoid the unnecessary image download, and errors reporting target state after an update.
