TST: gitrepo: Add test for runner with non-default protocol

The last commit dropped the GitRepo bits from test_protocols.py, which
means we're no longer testing that things seem to get wired up
correctly when a custom runner with a non-default protocol is passed
to GitRunner.  Add a test to test_gitrepo.py to make up for that.
