Fix ISO8601UtilsTest failing on systems with UTC+X

Previously ISO8601UtilsTest.testDateFormatString() would fail on systems
where the time zone is UTC+X because getTime() returned "2018-06-24" for them.

Additionally the tests which previously changed the system locale and time
zone have been rewritten to create a UTC calendar instead. Setting locale
seems to not be necessary because ISO8601Utils.parse(...) does not do that
either.
