Expression manager helpers do not require ContextConfig

So, if I understand correctly, right now in our tests we do things like:

    $action = $this->rulesExpressionManager->createAction('rules_entity_save', ContextConfig::create()
      ->map('entity', 'unknown_variable')
      ->toArray()
    );

The ->toArray() is needed because the signature for createAction() is ExpressionManager::createAction($id, array $configuration)

What you're proposing is to change the signature to ExpressionManager::createAction($id, ContextConfig $config) (with similar changes for createRule(), createActionSet(), and createCondition()).

This simply requires us to change the function signatures and move the ->toArray() call into the above ExpressionManager methods rather than calling ->toArray() and passing the result to the ExpressionManager methods.

Right?

That seems to be an almost trivial task if I correctly understand what you're proposing.

Committed. Feel free to re-open if I missed something.
