Fixed incorrect attachment loading integration test (#4453)

Browse Source 
* Fixed incorrect attachment loading integration test

`AttachmentLoadingTests.test that attachments retrieved over the network are not used for code` was a false-positive - it was incorrect on multiple levels. Fixing it required updating the finance:isolated CorDapp, at which point it was given the new MANIFEST metadata for V4, and moved out of the net.corda.finance namespace to avoid package sealing issues.

The new test exposed a bug in the LedgerTransaction verification logic. This was cleaned up as it was too easy to verify on the wrong instance.
