Updated taxonomy to get called after cache is flushed

The 'edit_term' action is called "after a term has been updated, but before the term cache has been cleaned."
The 'edited_term' action is called "after a term has been updated, and the term cache has been cleaned."

So when save_taxonomy calls get_term it was getting the old cached version not the updated version

Fixes #2264 (and likely others)
