Intermediate element not created when setting child projection

[zhsc]

I'm seeing an issue where when using @XBWrite the last element in the path isn't created.

Here's a test case to explain what I mean.

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.xmlbeam.XBProjector;
import org.xmlbeam.XBProjector.Flags;
import org.xmlbeam.annotation.XBWrite;

public class TestSetChildOnEmptyParent {

	public interface Child {
		@XBWrite("ChildData")
		void setData(String data);
	}
	
	public interface ParentWithRootElement {
		@XBWrite("Root/ParentData")
		void setData(String data);
		
		@XBWrite("Root/Child")
		void setChild(Child child);
	}

	@Test
	public void testSetChildProjectionEmptyParent() {
		XBProjector projector = new XBProjector(Flags.TO_STRING_RENDERS_XML);
		
		ParentWithRootElement parent = projector.projectEmptyDocument(ParentWithRootElement.class);
		
		Child child = projector.projectEmptyDocument(Child.class);
		child.setData("child data...");		
		
		parent.setChild(child);  
		
		System.out.println("Result: " + parent);
		
		// Doesn't generate <Child> intermediate level
		assertEquals( 
				  "<Root>\n"
				+ "   <Child>\n"
				+ "      <ChildData>child data...</ChildData>\n"
				+ "   </Child>\n"
				+ "</Root>",
				parent.toString());
	}
	
}

Like #51, I have a workaround:
Use
Child child = projector.projectEmptyElement("Child",Child.class);
instead of
Child child = projector.projectEmptyDocument(Child.class);

Again, I will try to make easier working with document projections and element projections.
