Trigger a profile update after syncing hashed password from the webhooks

[adamjudd]

As WordPress doesn't appear to support updating a users password with an already hashed password, it is currently updated by an SQL call when syncing users back to WordPress from FoxyCart. To ensure any functions that are being triggered on customer update are run, we should look at inserting a call like do_action( ‘profile_update’, $user_id ); after the SQL has completed to update the password.

FoxyShop also hooks into the profile_update event to sync back to Foxy, so we'll need to consider if triggering that extra API call is acceptable or not or if we can avoid it by temporarily removing the action.
