  Fix calling trace_dialog() after t_newtran().

The tracing relies on the REQUEST_IN callback - and this callback is triggered by t_newtran() before we decide (at script level) to do any tracing, so it will a try triggering (with no action).
The fix is to check (in trace_dialog()) if the tranaction exists (meaning the REQUEST_IN callback was already triggered) and if so, we trigger it again after setting all the tracing flags (to force the callback to actually do the job).
