[schema] Let RQLConstraint inherit from BaseRQLConstraint instead of RQLVocabularyConstraint
There is apparently no reason for RQLConstraint to inherit from
RQLVocabularyConstraint as it gets its `repo_check` method from
`RepoEnforcedRQLConstraintMixIn` and RQLVocabularyConstraint (which inherits
from BaseRQLConstraint) actually only overrides that method. So simplify
inheritance by removing a useless level of indirection.
Adjust cw_unrelated_rql accordingly, where it was that RQLConstraint inherited
from RQLVocabularyConstraint.

Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
