Honor overriden writeObject of JsonGenerator passed to setJsonGeneratorDecorator

[rdesgroppes]

The order in which JsonGeneratorDelegates are chained currently leads to disregard the writeObject method of the JsonGenerator passed to setJsonGeneratorDecorator.

The internal SimpleObjectJsonGeneratorDelegate indeed intercepts writeObject for quite a number of concrete types:

logstash-logback-encoder/src/main/java/net/logstash/logback/util/SimpleObjectJsonGeneratorDelegate.java

Lines 38 to 60 in 933a0f5

	public class SimpleObjectJsonGeneratorDelegate extends JsonGeneratorDelegate {
	public SimpleObjectJsonGeneratorDelegate(JsonGenerator delegate) {
	super(delegate, false);
	}
	@Override
	public void writeObject(Object value) throws IOException {
	if (value == null) {
	writeNull();
	return;
	}
	if (value instanceof String) {
	writeString((String) value);
	return;
	}
	if (value instanceof Number) {
	Number n = (Number) value;
	if (n instanceof Integer) {
	writeNumber(n.intValue());
	return;
	}
	if (n instanceof Long) {
	writeNumber(n.longValue());

// etc.

The present change therefore consists in moving any user-defined JsonGenerator to the top level of the delegation chain, leaving users the power (and therefore the responsibility) to adjust the output to their needs.
