APM: invert priority of sonification and enforced routing strategies

On device where the SONIFICATION (alarm, ringtone) strategy is
  supported by SPEAKER_SAFE, prevent switching output devices
  when the ENFORCED_AUDIBLE (shutter sound) strategy starts
  by having SONIFICATION at a higher priority than
  ENFORCED_AUDIBLE.

Test: take photos while phone rings
