- Delayed the call to UpdateGenericPropertiesAttributes() when creating Static Meshes

  after the collisions have been handled.
  This ensures that the created meshes have a valid BodySetup when updating the generic attributes
  and ensures that certain generic attributes/properties dont get overwritten by the collisions
  processing (ie, CollisionTraceFlag)
