Bug description:
  This is the public version of the following bug:
  https://bugs.launchpad.net/barajas/+bug/1393641

  After debugging seems the issue is that the application is getting
  deactivated and then activated (via Qt.application.active) when making
  a call in greeter (emergency) mode. This is causing problems for the
  app as it pops pages when it gets deactivated and causes the bug
  sometimes. The underlying problem is that this signal should not be
  occuring when the app is clearly in the foreground. It doesn't happen
  when not in greeter mode.

  An easy way to test is to install telepathy-ofono deb which is
  attached and set a fake emergency number to allow you to dial a normal
  number in emergency mode to help test by running this command at the
  shell:

  mc-tool set ofono/ofono/account0
  string:fakeEmergencyNumber=<yourNumber>

  Then adding console.log() to the applicationActive signal in dialer-
  app.qml will verify. When pressing the call button the app is
  deactivated then reactivated.

  Steps to reproduce:
  1) install attached telephathy-ofono deb
  2) run 
  mc-tool set ofono/ofono/account0 string:fakeEmergencyNumber=<yourNumber>
  and then follow secondary instructions (if any)
  3) lock phone
  4) press emergency call button
  5) dial <yourNumber> which will be a fake emergency call
  6) press the call button
  7) sometimes you will see a blank Emergency Call page after you press the call button, and when it works you will see the live call page
  8) adding debug to dialer-app.qml will show the active=false then active=true behavior after performing step 6.
