Fix SearchBuilder generation for hydra-head 12
Fix SearchBuilder generation for hydra-head 12

The hydra:install generator no longer inserts Hydra::AccessControlsEnforcement here, opting instead for the Hydra::SearchBuilder class which includes Hydra::AccessControlsEnforcement itself. However this causes a change in loading order and some behaviors of Blacklight::Solr::SearchBuilderBehavior are not overridden by Hydra::AccessControlsEnforcement as they should be in order to pass specs.

For now let's retain the existing SearchBuilder behavior.
