completion: silence "fatal: Not a git repository" error

It is possible that a user is trying to run a git command and fail to realize that they are not in a git repository or working tree. When trying to complete an operation, __git_refs would fall to a degenerate case and attempt to use "git for-each-ref", which would emit the error. Hide this error message coming from "git for-each-ref". Signed-off-by: John Szakmeister <john@szakmeister.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
