If no output is available, use the root screen geometry to determine the maximum...

This is necessary during a restart of i3 when restoring floating windows. In this situation, we restore the layout before setting up the RandR outputs which would set the window's size to 0, making it invisible.

Thanks to hwangcc23 and spudowiar for reporting.
