Trying to duplicate an emitter from the timeline crashes the editor. This looks to be the result of UMovieSceneNiagaraEmitterTrack not implementing the function SupportsType. 

Steps to Reproduce
  1. Open a Niagara system
  2. Click the emitter's track
  3. Select the emitter's section
  4. Right-click on the emitter's track
  5. Select "Duplicate"


The editor crashes
