ConditionalDocumentTest: Write with no version had misleading message

[sammefford]

Here is the message we're getting in the nightly build log:

testConditional(com.marklogic.client.test.ConditionalDocumentTest): Write with no version had misleading message

This looks to be a duplicate of #51 on the 7.0 branch. But I can't duplicate this. Can you, Sravan?

Ok, Sravan, fix applied, please git fetch/merge, then retest
