Setting `forkMode` to `ForkMode.NEVER` switches
`isolationMode` to `IsolationMode.CLASSLOADER`.
Classloader isolation mode prevented passing task's
logger to the unit of work.
Also it might resulted in multiple daemon instances starting
in parallel.
This change removes setting `forMode` (it was unnecessary).
Also a logger is used for the fallback message instead of printing it
to stderr. An assertion is added to tests, ensuring that
the fallback does not happen.
