unit-tests: Actually verify registered algorithms against test vectors

Previously, the {ns}.crypto_test.on_add option had to be enabled to
actually test the algorithms, which we can't enforce for the tests in
the test_runner as the option is already read when the crypto factory
is initialized.  Even so, we wouldn't want to do this for every unit
test, which would be the result of enabling that option.
