[test] Remove incorrect expectation

Remove test expectations whose behavior is not specified or contradicts
the Stage 3 PR https://github.com/tc39/ecma402/pull/349 which we plan
to land soon.

The Chinese calendar (and other calendars) now need to choose
different patterns for non-default calendars to support the correct
behavior.

-// Even though the calendar is Chinese, the best pattern search for formatting
-// should be done in the base locale (i.e. en or en-GB instead of
