Azure plugin: check nonces for search form
Azure plugin: check nonces for search form

This is probably a copy/pasta problem since it doesn't appear that the
requested values are ever used in this context, or even would be sent
to the search form, but I'm adding in the nonce checks and TODOs just to
be safe...for now.
