Fix bug when hggroup used with primitive graphic object (bug #42532).
* image.m, text.m, line.m, patch.m: __plt_get_axis_arg__ will return axis and
hggroup when 'parent' property is used. Select the first returned object
which is the axes, rather than passing both axis and hggroup to further plot
subroutines.
