GitInfo only reads branches in files /refs/heads/*; it should also read those in /.git/packed-refs. There are 4 tests in this commit to test this new "feature" and add some code coverage to other methods. Given this class tests Git behaviour and MediaWiki itself is versioned with Git, the test data are created during the tests and removed at the end to avoid interference with Git as CVS. Bug: T155747 Change-Id: Icccdf3ec797788582f836e2d8e267a1d714d50dc
