Cannot stream when retrieving metadata

[sammefford]

The following demonstrates that a large file fails to stream when metadata is also retrieved:

	XMLDocumentManager documentManager = client.newXMLDocumentManager();
	Transaction transaction = client.openTransaction();
	InputStreamHandle handle = new InputStreamHandle();
	DocumentMetadataHandle metadataHandle = new DocumentMetadataHandle();
	documentManager.writeAs("all_well.xml", new FileHandle(
		new File("test-complete/src/test/java/com/marklogic/client/functionaltest/data/all_well.xml")));
	documentManager.read("all_well.xml", metadataHandle, handle, transaction);
	InputStream stream = handle.get();
	while ( stream.read() > -1 ) {}

The last line just loops through reading the InputStream. But this line will fail because the stream is closed.

This is closely related to #725

As reported on SO, this was on the 3.0.7 release. The 3.0.8 release (OkHttp replacement) appears to have resolved this issue.
