[BUGFIX:BP:11.2] Shortcircuit work in SolrRoutingMiddleware

Shortcircuit work in SolrRoutingMiddleware like in PageIndexerFinisher: When a request does not have the X-Tx-Solr-Iq header, then it's not interesting for the Solr extension.

Background: Superflous logging 'Could not resolve page by path...' to Solr logfile.

Relates: #3202
Ports: #3339
