Fixing panics in test activities

[3vilhamster]

What changed?
I've fixed missing arguments in test worker implementations that caused tests to be flaky.

2. Set Enable Logging to be true so tests will get all trace log messages covered.

Why?
Improve stability of tests

How did you test it?
unit tests

Potential risks
