Prevent NPE if trying to restore an already restored deleted branch (#21940) (#21944)

Backport #21940

If a deleted-branch has already been restored, a request to restore it
again will cause a NPE. This PR adds detection for this case, but also
disables buttons when they're clicked in order to help prevent
accidental repeat requests.

Fix #21930
