ExUnit seeds each test process with {phash2(module), phash2(name), seed}.
parameterize re-runs the module per parameter set without changing the
test name, so every parameter set of a test started from the same :rand
state and drew the same random sequence.
Hash the parameters together with the name when they are present. Tests
without parameters keep their previous seed, so existing --seed
reproductions are unaffected.
