Preserve "Space" UI control value when editing Passphrase credentials

Summary: Fixes T9568. We just weren't setting this properly so it would default away from the proper value.

Test Plan:
- Edited a credential in a non-default space, edit form populated properly.
- Changed "Space", introduced an error, saved form, got error with sticky value for "Space" properly.
- Saved form with new space value.
- Created a new credential.
