Tests: fix up some setup/teardown method signatures

The `setUpBeforeClass()` and `tearDownAfterClass()` type methods should have visibility `public` and should be static methods, even when invoked via the annotations.

To be honest, I'm a bit surprised PHPUnit didn't flag some of these as errors, but either way, it's fixed now.
