Adjusted two tests in co19-dart2js.status
Adjusted two tests in co19-dart2js.status

One test was associated with co19 issue 727, which turned out to be
only partially correct; as a consequence issue 21197 is invalid and
was removed from status.  The other test was associated with co19
issue 731, which turned out to be wrong; as a consequence, a new issue
21271 was created and listed in status.
