Fix #125426: Update paths in animation when renaming IDProperty

Previously when renaming an IDProperty the existing paths in the
animation/driver system isn't updated, this leads to missing animation
after renaming the property. Now `BKE_animdata_fix_paths_rename_all`
will be called so the animation system records the updated name.
