Some tests failing depending on timezone

[sxhinzvc]

When running the build, the following tests are failing due to date mismatch, based on the timezone.

MappingMongoConverterUnitTests#projectShouldReadSimpleInterfaceProjection
MappingMongoConverterUnitTests#projectShouldReadSimpleDtoProjection
AbstractEncryptionTestBase#encryptAndDecryptJavaTime

The tests are asserting against LocalDate objects in my timezone, which is UTC-5.

For MappingMongoConverterUnitTests#projectShouldReadSimpleInterfaceProjection:

org.opentest4j.AssertionFailedError: 
expected: 1999-12-01 (java.time.LocalDate)
 but was: 1999-11-30 (java.time.LocalDate)

Good catch - the testsetup is using UTC to define the source date. This is different to what the default Jsr310Converters.LocalDateToDateConverter does when writing a LocalDateInstance leading to the offset.

There's 2 options.

Use the LocalDateToDateConverter to create the source data.

org.bson.Document source = new org.bson.Document("birthDate",
	LocalDateToDateConverter.INSTANCE.convert(LocalDate.of(1999, 12, 1)))
	.append("foo", "Walter");

or stick to the UTC date conversion and set up the converter differently to use native java.time codecs.

configureConverterWithNativeJavaTimeCodec();

org.bson.Document source = new org.bson.Document("birthDate",
	Date.from(LocalDate.of(1999, 12, 1).atStartOfDay().toInstant(ZoneOffset.UTC))).append("foo", "Walter");

For the encryption tests we should use the UTC based variant via MongoConverterConfigurationAdapter#useNativeDriverJavaTimeCodecs().
