[epiphany/mcatanzaro/reopen-closed-tab: 5/5] Properly set sensitivity of reopen tab context menu item

[Jan-Michael Brummer <jbrummer src gnome org>]

    Properly set sensitivity of reopen tab context menu item
    
    The new Reopen Closed Tab context menu item in the tab bar is not
    following the same sensitivity rules for the window menu item, resulting
    in crashes when it's called when it should be insensitive.
