The last part of `quickstart` feels weird. By consensus, we remove the
part that attempts to create a project directory and leave that step to
the user.
Currently, the fact that `os initialize` requires elevated permissions
forced us to require calling commands that reuse it, such as `device
init` and `quickstart` with administrator permissions as well.
This ended up causing issues like saving images in the cache that belong
to root, or initializing git repositories that requires `sudo` to
commit.
The solution is to call `os initialize` as a child process preppending
`sudo` within `device init`.

Currently, if `device init` was ran without an application argument, we
attempted to get the application name from the current directory, given
it was a git repository.
This approach led to confusions from time to time, so now we prompt the
user to select one of it's own applications from a dropdown instead of
checking the current directory in this edge case.

We were currently building this path ourselves, hardcoding the place of
the resin local per user directory instead of relying on the foundations
that `resin-settings-client` give us.
