test-convert-git.t: make copy detection deterministic

Since both 'bar' and 'bar-copied' matched 'bar-copied2', Git's copy detection
would sometimes result in 'bar' being the source for 'bar-copied2' and
sometimes 'bar-copied'. Change bar in a separate commit so that that would no
longer be the case.
