[Jonas Ådahl <jadahl src gnome org>]

commit 81923410f6e49ff3f2e393ed29e74253eb5e6931

    monitor-unit-tests: Test starting with lid closed
    
    Add a test case that checks that configuration works when the lid is
    initialy closed then later opened. This test case is disabled when the
    legacy configuration is used as it does not handle that situation.
