`make:factory` fails when there is more than one level of embedded classes

When attempting to generate a factory for a class that has a protected property of `Money\Money` type, I get the following error:

````
In LegacyORMDefaultPropertiesGuesser.php line 73:

  Property App\Entity\MyEntity::$price.currency does not exist
````

I'm using Foundry version 1.37.0.
