Use object type with name matching entity name by default

Is your feature request related to a problem?

When I added a second object type for ObjectType<User>, named ActiveUser, in addition to the existing User object type, my existing queries returning IQueryable<User> and Task<User?> started returning the ActiveUser object type.

(13.0.0-preview.52)

The solution you'd like

I assume that the engine finds two object types mapped to the User entity – if so, it should select the object type with a name matching the entity type by default. f.e., if the entity type is User and there is an object type with the same name (User), then use that object type, otherwise ...

... maybe it should also throw when there's no matching object type and there is more than one object type mapped to the same entity? Just selecting an arbitrary object type from a list seems unexpected.

Start by reproducing the issue with ObjectType and a second ActiveUser object type, then inspect the code paths that map entity types to object types for IQueryable and Task<User?> queries. Verify the documented cases: prefer a same-name object type, use the sole mapped type otherwise, and define the behavior when multiple differently named types remain.
