Taxonomy hook called too early on update

In function taxonomy_save_term(), the modules' taxonomy hooks are invoked immediately after the term_data table has been updated, but before updating term_relation, term_hierarchy, and term_synonym.

This is inconsistent with term deletion, which updates all those tables before invoking the taxonomy hooks (and which I think is a nice behavior).

The current behavior causes me a problem in a custom module I am writing, where my taxonomy hook needs to check the parents of the term being updated. To work around this, I moved the hook invocation near the bottom of taxonomy_save_term().

This issue seem to apply to the CVS version as well.
