Correctly handle issues when there is an exception in the Event

We seem to be getting unexpected errors of the type:

[ERROR] java.lang.IllegalArgumentException: No parameters found. The given test result for test ScenarioName.stepX does not seem to have been part of a Phased Test

| Exception is Event Phase | Symptm |
| ------------------------- | -------- |
| Start | Never Ending loop |
| WTF | Njava.lang.IllegalArgumentException: No parameters found. The given test result for test com.adobe.campaign.tests.integro.phased.data.events.TestNIE_Synchroneous.step2 does not seem to have been part of a Phased Test |

Situation: Exception in Event
Expected outcome:
An exception in an event should make the steps continue as before.
An error log should be provided informing us of this issue

Start by reproducing the exception during the Event phase, particularly around TestNIE_Synchroneous.step2 and the reported IllegalArgumentException. Trace how the event exception affects subsequent steps and verify that the steps continue while an error is logged without producing the never-ending loop or missing-parameters failure.
