RDS Upgrade - Edit Work Page issues

[eporter23]

Issues noted so far:

Attaching a new FileSet to an existing work fails
After trying to attach a new FileSet, the existing representative media/IIIF manifest no longer renders
Checking the representative media on the Work shows the correct selection (the original FileSet is still assigned)

Example of a work where I tried to attach a new FileSet:

https://curate-test.library.emory.edu/concern/curate_generic_works/7956djhb70-cor?locale=en

Making a minor metadata update to an existing work results in generic application error

@bwatson78 @jcrompton42 - I'm doing re-testing. Most issues seem resolved, but I am seeing some unexpected behavior related to manifest regeneration so I am continuing to investigate.
