On a call w/headphones, device button don't adjust volume

[Julien Funk]

1. Make a call to your mother with headphones in and a reasonably high volume (mother optional)
2. Wince at the high volume as your mother speaks to you
3. Attempt to reduce volume by clicking the 'volume down' button on the side of the phone

EXPECTED RESULT: volume goes down

What happened was the volume remained very high and I was forced to unplug the headphones to continue talking.

<https://wiki.ubuntu.com/Sound#primary-output>: "...the primary sound output ... is the device ... that should change volume when you press ... the volume buttons/rocker on a phone ... If you connect or pair headphones or a headset, or any audio output device except a secondary display, the primary output should change to that device."

The fix for this should come with an automated test so this regression doesn't happen again.

Just discovered this also affects all other modes, ie regular call volume and speakerphone. All 3 should be tested in automation.

This is not a regression, and known. Will be fixed once we're able to control the voice volume during a call (which I'm still working on).
