This issue just goes over all the currently incorrect
namespaces in test cases and:
1. Change the namespace to the correct one.
2. Move/rename it to correct location if needed (level 2 and down).
3. Remove not needed MOODLE_INTERNAL check when possible.
4. Remove file phpdoc when the file only has one class.
5. Make small adjustments in case the change of namespace requires it.
