fix bad interaction between nickTimer.Stop() and accounts.Logout()
Sequence of events: 1. client.nickTimer.Stop() 2. client.server.accounts.Logout(client) 3. accounts sees that client is no longer logged in, does client.nickTimer.Touch() 4. 30 seconds later, RandomlyRename resurrects the zombie client
