Description of problem:
Custom task event listener firing only for "afterTaskAddedEvent" but not any of the task update events like afterTaskActivatedEvent/afterTaskClaimedEvent/afterTaskStartedEvent  if we use "Per-Process-Instance/per-request"  runtime strategies while deploying kjar. Its working fine with singleton runtime strategies. 

Version-Release number of selected component (if applicable):


How reproducible:
With Per-Process-Instance/per-request runtime strategies

Steps to Reproduce:
1.Create custom TaskEventListener register it using kie-deployment-descriptor.xml
2. Deploy kjar with Per-Process-Instance/per-request runtime strategies
3. Start process instance and and check output

Actual results:
TaskEventListener not working as expected with Per-Process-Instance and per-request  runtime strategies

Expected results:
TaskEventListener should work with all runtime strategies
