Bug Description

Steps to reproduce:

1. phablet-shell to the phone
2. sudo apt-get install mir-demos
3. sudo stop lightdm
4. Run mir_demo_server_shell
5. Turn off the screen (power button)
6. From another phablet-shell session run mir_demo_client_egltriangle (or any other client)

Expected behavior: The client connects, gets a surface and draws (at low rate since screen is off)
Actual behavior: The client connects but fails to get a surface and exits

This is not an Android specific error, it's a problem with our default placement strategy (ConsumingPlacementStrategy) when there are no enable outputs.
