Revert "Fix weird daemon folder" (#1065)

The working directory deliberatly included the session ID in distributed
settings to avoid conflicts when multiple dataflows are run on the same
daemon.

The session ID is a unique identifier created for each dataflow.yaml
file. By using this ID as part of the working directory, we can ensure
that no other dataflow is running in the same directory. Sharing a
working directory between multiple distinct dataflows could easily lead
to unexpected behavior, e.g. by overwriting files of the other dataflow
run. So it's better to avoid this.

By using the session ID, the daemon will still be able to reuse build
artifacts etc of previous dataflow runs. So incremental compilation
still works.
