    Return a full reference when parsing triggers
    
    We're not returning a full reference for GtkNeverTrigger, but we are
    returning full references for mnemonic and keyval triggers; this means
    we're either going to leak mnemonic and keyval triggers if we consider
    this function a "transfer none" one, or we are going to trigger an
    assertion failure when finalizing a never trigger, if we consider this
    function a "transfer full" one.
    
    Let's be consistent, and always return a full reference to the caller.
