SearchIT.testNestedSubtree failing on jenkins.dataverse.org

This failure was reported on 8991919 but @donsizemore and I have been seeing it for several days if not weeks.

I'd feel remiss if I didn't mention that the phoenix server had a 500 error when running FileMetadataIT.testJsonParserWithDirectoryLabels but then I ran the job again and it passed (all on the same commit as above).

A couple quick observations:

• All the API tests are passing on phoenix.
• On EC2, SearchIT passes when run by itself.
• Simply adding a two second sleep doesn't fix it.

I just created pull request #6285

Weird bug. I left a long comment in the pull request with my take on it. I've been chatting with @sekmiller about it.
