Fix issue #389

1. Creating a date that crossed into previous/next months would be wrong depending on the user time zone and whether the previous/next month had a different number of days.  See `Construct from an ISO8601 local calendar date with UTC offset that crosses into previous month` and `Construct from an ISO8601 local calendar date with UTC offset that crosses into next month` for the new tests.
2. Clean up `JulianDate` unit tests so that they use `toEqual` rather than `equals`.
