codeintel: tell komodo about discarded scan requests
http://bugs.activestate.com/show_bug.cgi?id=100994

codeintel will drop document scan requests when newer ones show up for the
same document; we need to tell komodo about it when running OOP so that we
don't end up holding on to a lot of useless requests that will never get a
response.

codeintel: explicitly send empty responses for requests that don't need one

This makes sure we clean up the pending requests on the Komodo side
