fixed ajax

Browse Source 
widget will not display if taxonomy is changed and new term is not
selected. for some reason, the term doesn't select with ajax so the
$instance['term'] may end up mismatching with the $instance['taxonomy'],
which can throw lots of errors. for now, I'm dealing with this by
making the entire widget disappear if there is a problem.
