The original condition the property was based on was added to make the a11y switcher available in the login screen, though it did never work properly - after popping up the switcher, additional tab key presses were ignored. As we are now able to filter bindings much more selectively, we can simplify the check and drop the sessionMode property. https://bugzilla.gnome.org/show_bug.cgi?id=688202
