crypt32: Added Quoting-Tests

> First the normal then the test, or reverse?

Tests must pass with every commit.  In general, I prefer to see tests
first, with failing tests marked todo_wine.  Then the second patch,
with implementation, removes the todo_wines.  In this case adding
todo_wine might be more trouble than it's worth, so I'd do them in the
reverse order.  I'll comment on your try 2 again shortly, though.
