Summary: EventTargetWrapper and EventTarget were merged into one class that controls an `instanceHandle` reference and extracting a strong reference to it. This diff also decouples the operation of retaining a strong reference (with checking a `enabled` flag) from actual usage of this reference. This allows to wrap into a mutex only first part of this process and avoid possible deadlocks.
