Previously the flag was not honored. AudioSource::write() calls
-> SndFileSource::write_unlocked()
-> SndFileSource::nondestructive_write_unlocked() which calls
-> AudioSource::compute_and_write_peaks
This produced "cannot open _peakpath" messages during
session-archive FLAC encoding. Likewise closing an audio file
calls touch_peakfile(). Although this simply failed silently.
