shh.watch doesn't work properly.

[gavofyork]

The line:

shh.watch({ 'topic': [web3.fromAscii('chat'), web3.fromAscii('namechange')] }).arrived(function(f) { newName(f); });

in dapp-bin/chat/chat.html (Marek's branch) doesn't work. newName is not called when messages of that type arrive. Oddly, the line after:

shh.watch({ 'topic': [web3.fromAscii('chat'), myIdPromise], 'to': myIdPromise }).arrived(function(f) { newMessage(f); });

works fine.

Typing the former line in to the JS Debug Console gives a result as expected - newName is called when an appropriate message is received. The latter line includes promises, I can only assume that this makes the difference.
