[BUG] Conflicting case re-open button vs. non-closed statuses

Related to #1049 [BUG] Conflicting case closed button vs. case closed status

Describe the bug
Once a case has been "Closed" with the "Case Closed" button, you can still edit the case. If you change the status of the case to not Closed status, it does not actually re-open the case again.

To Reproduce
Steps to reproduce the behavior:

1. Go to a case and manage it
2. Change the case status to any status other than "Closed" and it just sets a new status
3. Click the "Reopen case' button
4. Case is now actually in an open status

Expected behavior
When selecting a non "Closed" status, invoke the "Reopen Case" dialog and actually close the case properly. Or, more accurately, make the manage dialog (at least the status?) read only when the case is closed. The entire case can be modified when is it in the closed status.
