COMMITTED: Fix for guild management window updates

[joligario]

Excellent work! Cheers!

This actually needs an addition ASAP. Gaeorn helped identify the problem yesterday and has this fix, but didn't get around to adding it yet.

I didn't verify the return was valid and World doesn't like null pointers =/

I've been unable to reproduce the conditions that would cause this to not return a valid client, it seems to have happened yesterday with some larger guilds, which isn't easily testable on a personal test server.
