We're currently working around this issue with the merges done by
Laércio. So now we need to disallow user switching but still be able to
return to a greeter on logout.

  LightDM fails to switch to greeter on logout if allow-user-

Bug description:
  In my multiseat system, if I logout on a non-seat0 seat (which has
  allow-user-switching=false by default), lightdm fails to start a
  greeter on that seat:

  DEBUG: Seat: Display server stopped
  DEBUG: Seat: Active display server stopped, starting greeter
  DEBUG: Seat: Stopping; failed to start a greeter
  DEBUG: Seat: Stopping
  DEBUG: Seat: Stopped

  I guess the problem is related to seat_switch_to_greeter() calls in
  session_stopped or display_server_stopped callbacks in seat.c. Switch
  to greeter should be always allowed on logout.

  NOTE: This was observed in LightDM 1.10.2 on Ubuntu 14.04, but I guess
  it also happens on trunk series.
