Bug description:
  Unity8 always crashes on second restart.

  Using the "restart unity8" command is very handy for applying
  environment variables and trying things out. The trouble is that it
  only ever works once. On the second use, Untiy8/Mir fails to start and
  in some cases the whole phone reboots (arale).

  On krillin:

  restart unity8
  restart unity8
  # Now the phone never restarts...
  $ tail ~/.cache/upstart/unity8.log
  [1440384396.950594] Platform Loader: Selected driver: android (version 0.11.0)
  Exiting Mir! Reason: Nested Mir and Host Mir cannot use the same socket file to accept connections!
  ERROR: QMirServer - Mir failed to start
  terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::logic_error> >'
    what():  Cannot use configuration before apply_settings() call

  
  On mako:

  $ system-image-cli -i

  $ restart unity8

  $ restart unity8
