tests: _FakeRoutes mock covers put/patch so the full suite can collect

The fake routes object installed into sys.modules as `server` only defined
get/post/delete; server.py also registers put (models) and patch (media), so
importing the real server.py during collection (e.g. test_server.py) raised
AttributeError and aborted the whole run. Add put/patch to the mock.
