Could this be changed to call `execute_after_hooks` prior to the final success message to the user? I'd like to keep exrm as the first and last thing that a user hears from when running `mix release` or `mix release.clean`, and keeps things consistent no matter how many plugins you may add. It also prevents the issue of "everything was removed successfully!" and then one of the plugins throws an exception for fails for reasons of it's own. Potentially confusing behavior.
