Username autocompletion stops working

[cwc]

This seems to mainly be a problem when there are multiple potential matches for the username. Say there are two users in chat:

alice
alice1

Autocompletion for al works as expected the first time, then the second time it autocompletes the second possible match (alice1 in this case). After that, it doesn't seem to work for any name.

Haven't seen this one in awhile.

So current situation is, as you say, the auto-completion works fine first time and second time, but then does not "loop" back to the first name again.

Expected behavior should be: al -> (tab) -> alice -> (tab) -> alice2 -> (tab) -> alice -> (tab) -> alice2 -> ...
However currently we have: al -> (tab) -> alice -> (tab) -> alice2 -> (tab) -> alice2 -> (tab) -> alice2 -> ...

Definitely a bug which should be fixed.

@hermansc Unfortunately this bug has mutated a bit in the new branch - want to take a look at it?
