edje: force update anchors when a API is called to get list of anchors

When anchors were not in the view port, they were not created,
and didn't have any geometry information. Because of this feature,
edje_object_part_text_anchor_geometry_get() gave unexpected result.
i.e. empty list.

Now, some APIs will force the updating of anchors to get
the correct information.
