test: move "doing A/B-Test" print statement below ignore-check

Move the print statement that states which A/B-Tests we're performing
below the check that filters out ignored test cases. This way, we avoid
claiming to do an A/B-Test for things that are later actually filtered
out (meaning no A/B-Test actually happens).
