Because we were sorting the Alt+Tab list by user_time rather than stacking order / MRU, it was possible for the currently-focused window to sometimes not be the first app in the list. Fix this by using meta_display_get_tab_list() to get the proper MRU ordering of windows on the current workspace, and then convert that to an ordered list of apps. https://bugzilla.gnome.org/show_bug.cgi?id=645026
