If I try to delete a branch that's already been deleted, I get this:

-----> error: unable to push to unqualified destination: feature/backspace
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to 'https://github.com/BCjwhisenant/video-js.git'

>> Error: Command failed: error: unable to push to unqualified destination: feature/backspace

Should we actually trap this into a more user-friendly message?
