conversation: Reverse messages in each log
While b7360ff1 took care of not discarding new messges the reversion of the list resulted in reversed entries for each log file (so the overall history was in the correct order but each converstion was reversed). We go this way around instead of using g_list_append() since the later is slower. Fix that by going through each log back to front.
