make "got branch -d" print reference name and value

Currently, "branch -d" operates silently.  With this change we match
the behavior of "ref -d" and "rebase -X"/"histedit -X" that print
sufficient information to allow recovering if the user fat-fingered
something.

I was about to copy-paste the code from delete_ref() into
delete_branch(), but I think we can just call delete_ref().

OK?
