git-storage: add helper function to delete remote branch

Browse source 
This will be used by the test to clean up test branches that are created
on the server. Since we aren't testing that functionality (it's not
something that Subsurface itself ever does) the helper prints out errors
it encounters, but doesn't report them back to the caller.
