Change default author substitution to avoid updating test hashes. Rather than '%s <%s%s>', just use '%s%s'. The two should be functionally equivalent. All tests pass. Added a comment about the handling of missing authors. This is tested by test_push_to_default in tests/test_push_command.py; it is treated the same as before.
