Add safe navigation to file_formats method

[jazairi]

Why these changes are being introduced:

We are calling uniq on file_formats, which
returns a nil error if that field does not exist.

Relevant ticket(s):

• TIMX-628

How this addresses that need:

This adds a safe navigation operator to the
file_formats method.

Side effects of this change:

I added a regression test, which creates a new
test file. It feels a bit odd not to test the
other Record Type methods in there, but doing so
seemed far out of scope of this ticket.

Pull request overview

This PR prevents RecordType#file_formats from raising when the underlying file_formats field is missing/nil by using safe navigation, and adds a regression test to cover the nil case.

Changes:

• Update RecordType#file_formats to use &.uniq instead of calling uniq on a potentially-nil value.
• Add unit tests for file_formats when missing/nil and when populated (deduplication behavior).
