Remove legacy scaffold links from edit forms after Rails Admin has been set up

[orenyk]

If you delete a user (from the link on the bottom of the "Edit User" form, e.g. /users/ID/edit), it tries to redirect you to the no longer existing user page (e.g. /users/ID). This should redirect to the users index, most likely (e.g. /users). Should be a quick fix.

This may become a non-issue once we have Rails Admin running and no longer need to have that functionality present in the general UI. Also, this may extend to the delete link for other models, that should be investigated.

Ok, this link is broken on master (I was using v3.4.4 when I encountered this). We must have removed the UsersController#destroy method so it doesn't do anything. I'm going to rename this issue to deal with cleaning up errant links post-Rails Admin implementation (e.g. when we finally have superusers).

EDIT This also stresses the need for integration tests, particularly those that test all links to make sure that they aren't broken :-)

As things stand, the delete link on the equipment model edit page returns a 404, I'm not sure if that's what I was getting when I encountered this issue before. Hopefully we'll have Active Admin / Rails Admin access later today though!

Categories has the same problem.
