select?collapse=... - fix NPE in Collapsing(FieldValue|Score)Collector
Patch is against branch_4x where CollapsingQParserPlugin line 230's searcher.getAtomicReader().getSortedDocValues call could return null. On trunk the line 230 call has been replaced (by
LUCENE-5666) and so the CollapsingQParserPlugin part of the patch is not required.
The TestCollapseQParserPlugin change could go to branch_4x only or branch_4x and trunk.
