repos: fix abuse of dead 'repo' routing The repo "show" controller didn't do anything and was unused. There was a routing GET entry for it but it was only used for generating URLs for DELETE and PUT operations that have separate controllers that happen to have the same URL. Use the right routing entries when generating URLs and drop the dead code.
