fix: setup instance with human an machine user at creation (#7997)

# Which Problems Are Solved

Currently on instance setup there is only a possibility to either use a
human or a machine user and not both at creation.

# How the Problems Are Solved

The logic in the instance setup is refactored and changed so there is
not an exclusion.

# Additional Changes

Refactoring, so that unit testing is possible to add for the different
elements of an instance setup.

# Additional Context

Closes #6430
