NPE on ElasticsearchIntegrationTest

[cfstout]

Seems that there is an NPE in the waitForDocs method of ElasticsearchIntegrationTest. I discovered when trying to write a test case using this class which calls the method: waitForDocs(final long numDocs) which propagates down a null value to this portion of the code.

Problem seems to surface on this line:
https://github.com/elasticsearch/elasticsearch/blob/master/src/test/java/org/elasticsearch/test/ElasticsearchIntegrationTest.java#L999

As noted in the documentation indexer is Nullable, but if null here, we see a null pointer. I think in the null case we could default to 0 and the code would work as documented, but wanted to get some feedback before making the change.
