Users: issues with changing user status (from inactive to active)

Overview: bug reported by the FLO libraries, and the issue is also present in FOLIO Snapshot.

Steps to reproduce:

1. Login to FOLIO Snapshot, go to the Users app
2. In the Search and filter pane, then select Inactive users
3. Pick any given Inactive user,
4. When viewing the user record in edit mode

Expected behavior:
It's possible to change the Expiration date, and change the status to be Active. And I can save my updates, and the User now has the status as being an Active user.
