Philip Chimento 27f0104bc6 Regularize Temporal.*.from() object cloning tests
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.
