Fixed failing test, and moved to full-on PSR-4 structure

- Failing test due to improperly resolved class names; resolved them.
- Moved `Module` and `ModuleTest` to their respective `src/` and `test/`
  directories, where they belong, and removed the classmap autoloader definition
  for the former.
