    authPrompt: Clear _queryingService on verification failure
    
    A conversation is finished after failing, and we are expecting a new
    one to be started shortly after. However if we encounter an existing
    reference to a previously set _queryingService, we will clear the
    password entry, which might already contain a partially typed password
    at that point. The behavior does make sense in the case of conflicting
    conversations, but in the failure case it is both unexpected and
    annoying, so clear _queryingService early to prevent this.
