Adjust Both Coordinates for Two-Cell Anchors (#2909)

Fix #2908. When support for two-cell anchors was added for drawings, we neglected to adjust the second cell address when rows or columns are added or deleted. It also appears that "twoCell" and "oneCell" were introduced as lower-case literals when support for the editAs attribute was subsequently introduced.
