phone locks after switching away and back to active call

[Bill Filler]

build 139 on Krillin

Steps to reproduce:
- unlock phone
- receive a call
- answer the call
- swipe away the dialer to the dash
- press the Active Call bar at the top to go back to call

Expected results:
- dialer is displayed, phone remains unlocked and indicator panel is visible

Actual results:
- dialer is displayed, but the indicator panel is not showing
- no way to get back to shell or other apps
- have to press back button in dialer which brings you to the greeter where you have to unlock the phone to continue

[Bill Filler (bfiller)]

Other thing I noticed, which may be a separate bug:

- lock the phone
- receive a call on the phone and answer it
- dialer is shown, but the indicator panel is missing. It should be displayed even when the phone is locked.

[Michael Terry (mterry)]

That second issue, of the panel being missing -- the shell forces fullscreen mode and disables the indicators when in emergency mode. For two reasons:

1) Less security surface. The emergency mode (without an actual split greeter) is kind of a hack. We actually unlock phone and let the user in, but only for the one app. We try to treat it as if the greeter were up as much as possible. But just in case we screwed something up, we figured we were better safe than sorry and disabled the indicators and launcher in emergency mode.

2) Less distractions. When in emergency mode, we figured the risks of accidentally interacting with launcher or indicators when in a stressful situation were not worth it. Granted we use the same "emergency" mode when receiving a call which will not have the same considerations.

But the panel shouldn't be black. The dialer app is supposed to request fullscreen mode so that it takes up the whole screen.

https://code.launchpad.net/~boiko/dialer-app/fullscreen_emergency_mode is too big to be considered and seems to include more than the actual targeted fix. Can you pls clarify if we need to change all of the 3k LOC?

[Bill Filler (bfiller)]

The diff is a mistake as it incorrectly includes the pot file, updating now..
