Use platform aware class in tests

[theseion]

Fixes #618

Thanks for the PR, Max. I had already adjusted the tests via 3f277b9, but cherry-pick the relevant bits from this PR via e03bd96.

Nonetheless, the Pharo 12 builds still fail:

That's because those images are not the alpha images. The URL for the Pharo 12 images ends in 120. We should probably remove Pharo64-12 from the list of images, or at least from the test matrix. That image hasn't been updated in a while.

We should probably remove Pharo64-12 from the list of images, or at least from the test matrix.

I'm not sure I understand. Is Pharo 12 considered stable or not? Nonetheless, the tests are failing in a weird way in that image. Are you sure the code you recently added to find classes in categories is doing what it should be?

[theseion]

No, Pharo 12 isn't stable yet. Alpha and 12 are the same thing, but there is already a 120 image, which isn't updated by the nightly build. That means that Pharo64-12 is not the same thing as Pharo64-alpha.

Yes, the code should be fine. It works for the alpha build.
