Fix two test failures due to the merge:
* StandaloneNoteDbMigrationIT assumed that GCing All-Users would prune
all loose objects, whereas in recent JGit versions, unreachable
objects are left loose unless gc.pruneExpire is set to "now". Do this
in the tests.
* AbstractQueryChangesTest#watched modifies the user's project watches.
In the master branch, watches are now stored in the AccountState
instance, so we need to recreate the IdentifiedUser in order to reload
the AccountState.
