Add tests for SES, and fix one more cell renaming bug.

* lisp/ses.el (ses-relocate-all): In case of insertion, do not
relocate value for named cells as they keep the same symbol.
(ses-rename-cell): Set new cell name symbol to cell value --- do not
rely on recalculating.  Push cells with updated data --- cell name,
cell reference list, or cell formula --- to deferred write list.

* test/lisp/ses-tests.el: New file, with 7 tests for SES.
