Avoid accessing freed memory when being replaced

Browse Source 
If we are replaced via the window manager selection, then we close
the MetaDisplay before meta_finalize() runs. We should be careful
not to try to close the display again (and access already freed
memory) in that case, so clear the global 'the_display' variable.
