suggestion to address `get_legend` issue wilkelab#205 - added `is_zeroGrob` function - modified `get_plot_component` to filter all nonZero Grobs. - added return_all option to `get_legend` function. A side effect is that now fails test "get legend" however, noted in comments the test is "more of a duct tape solution than a reflection of the intended behaviour". I think for almost all components it would be reasonable to return first nonZero Grubs by default, the option to return all also enables the user to grab all labels that match.
updated test so now null is always expected
