Title: [t2024] Remove 'trackeventcreated' event.

1. Removed references to `trackeventcreated` event.
2. Editor.editTrackEvent called directly when trackevents are created.
3. butter.generateSafeTrackEvent.
4. Media diverts to using defaultTarget when plugin drop occurs.
5. Timeline's onplugindropped event uses generateSafeTrackEvent.
6. Some protection for defaultTarget.
7. Tests.
