[ENG-114] Fix for non-sequential version identifiers

[Johnetordoff]

##Purpose

Make sure the UI doesn't break from non-sequential version identifiers

Changes

I've made some changes to the way we pull version information so the system won't break when used by a user with non-sequential ids. For more details see the ticket.

QA Notes

We should be able to identify/create some bugged version to test with. Doing this on prod will need someone to do a query with prod data

Once a bugged file version is created you should be able to trigger this bug by going to the revisions page on a bugged file.

Documentation

Not user facing

Side Effects

This is essentially a band aid for the problematic version ids.
