Saving New Preparation without CO # causes IntegrityError

[pashiav]

Describe the bug Saving a New Preparation through Data Entry causes an IntegrityError. This seems to happen because the Preparation requires a Collection Object number, but there is no field for it.

To Reproduce Steps to reproduce the behavior:

1. Go to Data Entry -> Preparation (https://umherb11024-v794.test.specifysystems.org/specify/view/preparation/new/)
2. Fill in the required fields then click Save
3. See error

Expected behavior Either:

• There should be a save blocker OR
• A New Preparation that requires a CO should not be allowed at all. The user should be notified that they cannot enter preparation data through New Preparation and should be directed to New Collection Object instead.

Any thoughts? @specify/ux-testing
