Description

When creating the emitter's track widget we search for the stack view model's root entry, but the stack view model pointer is null, so we crash. 

Steps to Reproduce
  1. Open a Niagara systems
  2. In the Niagara timeline select an emitter's track, and copy it (ctrl+c or through the right click menu)
  3. Paste the emitter underneath (ctrl+v or through the right click menu)

RESULT

The editor will crash
