fix: correct runtime check for resolve strategies

[gzomer]

The documentation states that when both centralized and modular strategies are enabled you have to either implement isTypeOf in all members or implement resolveType in the abstract type.

isTypeOf on all member types & resolveType on abstract type required until either all members have isTypeOf implemented or resolveType is implemented.

However, the current implementations is as follows:

if (
      (resolveTypeImplemented === false || typesWithoutIsTypeOf.length > 0) &&
      features.abstractTypeStrategies.isTypeOf === true &&
      features.abstractTypeStrategies.resolveType === true
    ) {

Instead, it should only trigger an error when both checks are false (no resolver implemented and there are missing types).
