Almost had an infinite loop in nick_get()

[trygveaa]

When setting this: <@root> nick_format = `%full_name_(%group)'

And reconnecting to the account (happened with all I tried - msn, gtalk and fb), I got this error:

<@root> Warning: Almost had an infinite loop in nick_get()! This used to be a fatal BitlBee bug, but we tried to fix it. This message should *never* appear anymore.
