testbench improvement: define state file directories for imfile tests
Not all imfile tests have state file directories or a global working
directory defined. This results in usage of the default location.
While state file names should be sufficiently different, there is still
some riks of using the same name in different tests. That becomes
problematic if tests are run in parallel (and they are run in
parallel inside the regular CI).
