Write Git instead of type(self.git)

Some tests in test_git.TestGit used type(self.git) while others
used Git. This changes them all to use Git. The distinction could
be relevant if self.git were set as a mock, but this is not being
done, and if it were, it is not obvious which would be preferred.
The intention of the existing tests is to test attributes of the
Git class, so this picks that simpler expression.
