aliases: Fix gfrb/gfrbi with slash-delimited branches

Multi-part branch names would be incorrectly split on the last slash and
not the first, causing these aliases to do the wrong thing. These need
the remote name which is the first element. Everything after the first
slash is the branch name, not the last slash.
