SnapdragonCamera:Fix no recording thumbnail when capture during recording.

The default video file name is generated by the start recording timestamp.

Need to use the recording stop timestamp to generate the video file name
to rename previous.Then camera will update the media provider when stop
recording in order to display the new thumbnail in time.
