Normally, tests which are written non-dependent to other tests can use
minimal-tests and should use as well. However, in our test settings
base-schedule is being used which may cause unnecessary dependencies and
so unrelated errors that developers don't see in their local environment
With this change, default setting will be minimal, so that tests will be
free of unnecessary dependencies.
