    prefs: fix crash when importing old filter expression preference
    
    When the filter label was missing, it would result in a crash
    (use-after-free) while reading the next expression. For example:
    
        gui.filter_expressions.label: Not-Junk
        gui.filter_expressions.expr: tcp.flags.reset==1
        # note: missing label preference
        gui.filter_expressions.expr: dns
    
    While at it, do not duplicate the filter expression,
    "filter_expression_new" has always been copying it.
