    recent: Fix crashes when DISPLAY is not set
    
    Recent backend is based on GtkRecentManager and calls gtk_init.
    Unfortunatelly, gtk_init aborts with "cannot open display: " warning
    if DISPLAY variable is not set. It happens e.g. when recent backend
    is spawned from a terminal without a graphical session. Systemd user
    units make this even worse and this happens also in graphical session
    if gvfs was running before the graphical session starts...
    
    Let's remove gtk_init call. It seems that GtkRecentManager works
    properly without it, because the display isn't really needed for it.
