Enable enforcer maven plugin for Neo4j

Description

It was disable because the Lucene version in Neo4j was different from the one used by Hibernate Search, now the tow versions are aligned and we should take advantage of it for as long as we can.

Enabling the plugin will allow us to keep track when the compatibility will end.
