change the logic for a capture buffer flush to disk when a locate is occuring

Browse Source 
We can't check for Session::actively_recording() because punch out may have disabled that. Rather
than add logic to check if a flush is needed (which is not much different than the code that runs
as part of the flush to disk), just do a flush anyway.
