If /CTOG Q is enabled, channel topic cache can get stale (and titlebar topic out of date)

Set /CTOG Q on
Have /WTOG T on

Change the topic. Notice the topicbar doesn't update.

This is to be expected to a degree, the client doesn't see things it's ignoring.

Have to think of how the logic of this should work some more.

Fixed this by removing TOPIC from /CTOG Q
