	Fix a crash when deleting a chart. We may be in a state where a chart
	has axes and grid lines, but axis_set is GOG_AXIS_SET_UNKNOW.

	* goffice/graph/gog-axis-line.c (gog_axis_base_get_crossed_axis_type):
	exit early if axis_set == GOG_AXIS_SET_UNKNOW.
	(gog_axis_base_view_point): ditto.
	(gog_axis_base_view_padding_request): ditto.
	(gog_axis_base_view_render): ditto.
	* goffice/graph/gog-grid-line.c (gog_grid_line_radial_render): ditto.
	(gog_grid_line_circular_render): ditto.
	* goffice/graph/gog-chart-map.c (gog_chart_map_new): return NULL is
	axis_set == GOG_AXIS_SET_UNKNOW.
