Add tests for invalid calendar ids, include unknown calendar id. (#4797)

Also homogenise format of existing tests, adding the test for unknown calendar id u-ca=notacal.

This addresses issue #3896

Two tests (argument-string-* and argument-propertybag-* are added or addended
for the following.

    Duration.(round, total)'s option relativeTo,
    Duration.compare's option relativeTo,
    PlainDate.prototype.(equals, since, until),
    PlainDate.(from, compare),
    PlainDateTime.prototype.(equals, since, until),
    PlainDateTime.(from, compare),
    PlainMonthDay.prototype.equals,
    PlainMonthDay.from,
    PlainYearMonth.prototype.(equals, since, until),
    PlainDate.(from, compare),
    ZonedDateTime.prototype.(equals, since, until),
    ZonedDateTime.(from, compare)

The tests calendar-invalid-iso-string.js with string arguments are addended
for each constructor and each withCalendar (these do not take argument bags).
