Creating, modifying or deleting a collection type in Sirenia takes a really long time

[rjkati]

Descriptive summary

When I attempt to create, modify or delete a collection type in Sirenia, the action takes a really long time to complete.

Steps to reproduce the behavior in User Interface (UI)

1. Log into your local build of Sirenia as an admin
2. Navigate to Dashboard -> Collection Types
3. Try to do an action on the Collection Types page

Note that each task completes as expected, it just takes forever to do so.

Actual behavior (include screenshots if available)

All testing occurred in my local build of Sirenia using Hyrax 5.0.1 in Google Chrome on Windows

• Loading the collection types page: 35 seconds
• Creating a new collection type: 7 minutes, 8 seconds
• Modifying a collection type (I disabled Sharing on the Settings tab): 6 minutes, 17 seconds
• Deleting a collection type: 1 minute, 43 seconds

For each task, Docker displays this message while running the task, in case it is helpful:

@rjkati - I tested some of this in our deployed Emory application also, so it's probably a little faster than the docker image, but still quite slow.
Loading the collection types page: 40 sec
Create a new Collection Type: 2 min 49 seconds
Modify the new Collection Type (added a badge color): 58 seconds
Delete the new Collection Type: 44 seconds

I've noticed a similar pattern in the logs while running sirenia specs, so this likely has a large impact on rspec run time and performance in general.

I think I found the source of the problem and have a PR to resolve it: #6925
