bitbake: fetch2/git: Improve handling of unresolved names verses branches

Currently the fetcher doesn't distinguish between names that the fetcher
needs to resolve verses branch names that the user specified.

This meant that if you specify a tag and a branch, the fetcher broke. This
separates the two so that the branch name is preserved and can be used in
appropriate places.
