There were some code paths where the original
MirroredSolrRequestwasn't preserved inIQueueHandler.Result. This resulted in NPEs when re-submitting to a dead-letter queue, but IMHO the fact that you could produceResultwith a null item was trappy enough so I refactored the constructors to avoid it.This PR also drops requests for non-existent or read-only collections to avoid unnecessary errors from Solr.
