Fix UserSpeechMs growing indefinitely in Server VAD mode

Browse Source 
TurnStartTime was only set in StartListening(), which is called once.
In Server VAD + interruption mode the mic stays open, so TurnStartTime
was never updated between turns. Now reset TurnStartTime when the agent
stops speaking (normal end + interruption), marking the start of the
next potential user turn.
