SoundRecorder: Fix timestamp mismatches in recorder and music app

Recorded file in record app is named after the timestamp when user
starts recordings, but the timestamp string to be inserted into media
database depends on the time when user save record.

Need to keep the consistency of timestamp to avoid mismatches.
