Applying Humanoid Animation Type to this fbx generates unexpected error for "Hips", when the hips are actually properly mapped.

repro:
- open attached project
- select Willard in Project
- In Inspector> Rig ...
- set Animation Type to None, Apply.
- set Animation Type to Humanoid, Apply...
bug/error: "Invalid Avatar Rig Configuration. Missing or invalid transform: Required human bone "Hips" not found."
see attached gif

if this does not repro the first time, copy Willard.fbx into a new project, re-do repro steps.

clicking the Animation tab, then the Rig tab again, updates the UI and the error message disappears... giving you the expected result.
