[Test issue] ParseJSON(<value>, DateTime) or AsType(ParseJSON(<value>), DateTime) don't follow test setup 'TimeZoneInfo'

[CarlosFigueiraMSFT]

Follow up to !3067 - the tests below failed, in tests with a #SETUP: TimeZoneInfo("Pacific Standard Time") directive:

>> AsType(ParseJSON("""2000-12-31T15:59:59.999"""), DateTime) = DateTimeValue("2000-12-31T23:59:59.999Z")
true

>> ParseJSON("""2008-01-01T04:12:12.100""", DateTime) = DateTimeValue("2008-01-01T12:12:12.100Z")
true

The directive isn't passed correctly to the runtime, so we should investigate why this is the case.
