[sf] additional fixes for framerate propagation in new fe

We have to update the parents when their child is reparented. The
parent doesn't have a change flag since a child in most cases does
not affect its parent. To ensure framerate gets updated correctly,
always update framerates if there are any hierarchy changes.

Also add more tests to exercise this path.
