ISPN-4464 Unify test suite for remote and embedded DSL based query tests

* Fixed test so it will properly close cache manager and continue build
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging
writes to log4j in the cdi module (and dependents).

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
