Flexmodel generates property with underscore if the field is a foreign key

[deborahvandervegt]

If an underscore is being used in a field and that field is a foreign key to another object, like in the next example, Flexmodel generates a property in the Entity which also contains an underscore.

<field name='object_created_by' label='Gereserveerd door' datatype='OBJECT.User'/>

    /**
     * @var User
     */
    private $object_created_by;

If the field is not a foreign key and an underscore is being used the property looks like:

<field name='object_created_at' label='Gereserveerd op' datatype='DATETIME'/>

    /**
     * @var DateTime
     */
    private $objectCreatedAt;
