MNT: Fix double evaluation of _LazyTickList

Closes matplotlib#28908. It seems the read-access to `instance.majorTicks` per `instance .majorTicks.append()` still triggers the descriptor, even though `instance.majorTicks = []` previously should have rebound the name. For details see matplotlib#28908.
