[FastTextAutosizer] Update expectations for two FTA table tests

This patch updates the test expectations for two FTA table tests after [1].

The old autosizer would autosize some table cells that the fast autosizer
doesn't autosize. This patch simply updates the virtual expectations to
enforce that.
