[Bug 1487111] Re: camera app unresponsive if trusted prompt left for some time


Note, we've added a workaround in qtubuntu-camera (in silo 40) to make
this problem better (no hang) but does not fix it completely.

The following will occur:

1) try to record a video
2) don't press the trust prompt
3) let your phone go to sleep
4) wake it up and open camera
5) press on trust prompt (either decision)
6) now you'll have to press record button again as we detected the timeout and did not record the video
7) the videos after this will have no audio until you reboot regardless of prompt choice or settings change, as pulse is in a messed up state

Bug description:
  image95/arale (also on mako)
  i see this for both the audio trust prompt and the video trust prompt
  1. launch camera
  2. don't touch trust prompt - set phone down for 5 min
  3. after time, select "accept"
  (alternately - select accept on camera, hit record and wait for audio prompt, step2)

  expected - app continues
  result - app is frozen, shell is still responsive, camera service spinning 50% cpu
