Fixed: Solved segfault on accept/reject (BMC#3472)

BMC#3472 - Dialer application will quit if user reject an
           incoming call in call history panel

- Turns out that until an MSceneWindow has first appeared(),
  it's orientation() method will segfault.  Probably a but in
  MSceneWindow that needs to be filed, but this fix is sane and
  not too hackish anyway, since we also update on the appeared()
  signal.
