cellrendererpixbuf: do not clear the icon helper twice

Do not call _gtk_icon_helper_clear explicitely when the properties
are set, since the corresponding _gtk_icon_helper_set_* method
already calls clear internally.
While at it rename the reset function to make it clear that it
is calling notify for the previous image type and avoid the
notification if the image type is not changing.
