Test: scheduler: Update tests after new stop_if_fail argument

Some scores are repeated since we're able to back out of a failed early
assignment now.

Only one test changes otherwise. bug-1822 has a score change from
-INFINITY to 49. However, the partially active group is still not
allowed to promote, which is the purpose of the test.
