Each from() method except Calendar and TimeZone should test that when you pass an instance of that type, the return value is a clone of that instance, and a distinct object. These tests existed already for some types; regularize them and add the ones that didn't exist yet. In order to test the referenceISODay of a PlainYearMonth we add an argument to TemporalHelpers.assertPlainYearMonth.
