Expand get_remote_merge_branch to compute the tracking branch to merge
when called without arguments (or only the remote name). This allows
"git pull --rebase" without arguments (default upstream branch) to
work with a rebased upstream. With explicit arguments it already worked.
Also add a test to check for this case.

Changes since v1:
- Hopefully provide a more useful and correct commit message
Changes since v2:
- Add sentence about the "with explicit arguments" case
- Move the test about two branch to a different patch
- Restore the executable bit
