Fix T46320: New Depsgraph: Auto-IK doesn't work

The issue is caused by transform tool temporary affecting on the pose
constraints, which actually changes the way how pose is to be evaluated.

This isn't ideal patch from the performance point of view, but only
limited to the new depsgraph, so we've got some time to work on partial
graph updates.
