Revert "TAStudio: Update self after loading a state. There doesn't seem to be any reason to not update TAStudio, and doing so fixes two bugs that were most evident when loading the state for frame 0:"

This reverts commit bb226f6.

This regressed #2965. Will attempt a different fix for the mentioned issues that doesn't regress anything.
