Description

Right now, recovery can be kicked off when SolrCore is already closed or duing closing a SolrCore. It will be more safer to close all event listeners that can kick off recovery or indexfetcher (replicateFromLeader) before we close SolrCores.
I think it will fix the problem of SOLR-13276 test failures recently.
