IMHO these can be considered unit tests; they were already fast, but now
they're executed in an instant.
This requires several changes: 1 - delay retrieving messages in
AFPUserVisibleException, to avoid having to deal with i18n whenever we
want to test exceptions; 2 - Use some DI for Parser and Tokenizer.
Equivset-dependend tests are also moved to a new class, thus helping to
fix the AF part of T189560.

Some of them are actually too simple, and may be unuseful in tricky
situations. This patch adds a lot of test cases to provide an (almost)
bombproof safety with future patches.
