Remove a dedicated buildPanic and use buildFinish instead
What does this MR do?
~~This fixes a small ~bug related to handling panic of executeScript().~~
Prior to this change the if executeScript() would panic the buildFinish
would never be executed, and thus CI job would be waiting on a WaitForBuildFinishTimeout.
This considers panic to be a regular buildFinish behaviour, immediate to take place.
