Description

Normal deleteByQuery commands are subject to version constraint checks due to the possibility of out of order updates, but DUH2 has special support (triggered by version=-Long.MAX_VALUE for use by tests to override these version constraints and do a low level IndexWriter.deleteAll() call. A handful of tests override SolrTestCaseJ4.clearIndex() to take advantage of this (using copy/pasted impls), but given the intended purpose/usage of SolrTestCaseJ4.clearIndex(), it seems like the the base method in SolrTestCaseJ4 should itself trigger this low level deletion, so tests get this behavior automatically.
