      Description

      as part of some refactoring done in LUCENE-7643, an optimization for was introduced for some single valued cases, which introduced an NPE risk surfaced in SOLR-10013.

      I plan to fix SOLR-10013 by disabling this optimization with a comment pointing to this issue, and commit with it a lucene level test steve wrote that usualy fails with the optimized code (since it doesn't fail 100% of the time, it suggests the failure is related to the RandomizedIndexWriter - the docs and queries are fixed)
