Convert another configuration test to a unit test

[cyrille-artho]

This is useful in particular to find issues with static fields that do not get reset when re-running run (from a test harness) instead of main as a process. The same issue may appear (much more likely/often) with Main.run in Modbat.

This seems to work, but please remove the redundant test Choose00-2 now and use instead a test of the new setWeight models.

We need one more configuration test to close this issue. There are several Modbat tests that presumably cover configuration issues, but no smaller tests for only the configuration.
The best way to have another test is to migrate an existing test (from bin/test.sh) and remove it there.
The current test should also be reviewed and removed from bin/test.sh. Log files that are no longer needed should also be removed.
