Update redirect/cancel URIs for repository dialogs

Summary:
Ref T10923. Some of the dialogs ("Deactivate Repository", "Test Automation", etc.) had cancel or redirect URIs which I missed originally.

Go through them and make sure they all point to the right places.

Also removed one unused controller which I missed the first time around.

Test Plan:
  - Opened all these dialogs in a new tab with Command-Click.
  - Clicked every "cancel" and "submit" button on all of these dialogs.
  - Got consistently sent to the place I came from.
