fix: Fix transformed properties assigned to incorrect entities.

[stephenh]

When we lazy-initialized properties, i.e. like:

     "class Author {
         get numberOfBooks() { return this.__data.relations.numberOfBooks ??= hasAsyncProperty(() => {
             return 1;
         }); }
     }

I'd forgotten that internally hasAsyncProperty & friends using the currentlyInstantiatingEntity to know what to hook themselves up to (because this makes for a new API than always passing this as the 1st arg of every proepty).

So, properties got hooked up to "whatever random entity was last instantiated".

So we now fix-up the currentlyInstantiatingEntity in the getters:

     "class Author {
         get numberOfBooks() { return (setCurrentlyInstantiatingEntity(this), this.__data.relations.numberOfBooks ??= hasAsyncProperty(() => {
             return 1;
         })); }
     }
