Describe the bug
A clear and concise description of what the bug is.

On fields with type LocalDate, tests are using the method

public static String formatDateTime(Temporal temporal) {
    return DATE_TIME_FORMATTER.format(temporal);
}

DATE_TIME_FORMATTER using the pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z' which results on an error UnsupportedTemporalType Unsupported field: HourOfDay

TestUtil class should have another method to deal with LocalDate

    private static DateTimeFormatter DATE_FORMATTER = DateTimeFormatter.ofPattern(LOCAL_DATE_FORMAT)
            .withZone(ZoneId.of("UTC"));

    public static String formatLocalDate(Temporal temporal) {
        return DATE_FORMATTER.format(temporal);
    }

To Reproduce
Steps to reproduce the behavior:

1. create a field with LocalDate type.
2. Generate the entity
3. run mvn clean install
4. See error

Expected behavior
All tests should pass
