Simplify MovePart code

Browse Source 
InnerActivity and UpdateCenterLocation made this
overly complex and hard to read & debug.

This also fixes a bug that would make an outdated
facing being passed during OnComplete (because
InnerActivity was cached before UpdateCenterLocation
could set the correct final facing).
