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
Configure event sender as an async Listener

* Ordering is only guaranteed as long as the async listener executor
is configured with 1 thread, which is the default.
* By using async listener, construction of the event and sending it
is taken out of the critical path of the Hot Rod client request.
