Handle mutation failure

[paullebras]

Hello!

Following the implementation of graphql-constraint-directive, we encountered a failing test. This test aimed to ensure that mutations would fail under specific conditions.

Instead of correctly handling the mutation failure with this message : Schema is not configured to execute mutation operation. It would throw the following error :

{ "errors": [ { "message": "Cannot read properties of undefined (reading 'getFields')" } ] }

These changes address this issue, ensuring that mutations fail gracefully. We also added a test to validate this behavior.
