Title: Fix for issue #1218

If there is something in clauses['join'] append the join from
woocommerce instead of overwriting it, just as for the clauses['where']
section bellow.

This happens if you use comments translaton with wpml, the clauses['join'] part filled in by wpml is overwritten by woocommerce.

Please review or comment how we can improve the fix.
