Item Language fallback doesn't work on SitecoreChildren extended models

[AronBender36]

Ex:
-- Auto-generated interface
` public partial interface IProductSelection : IGlassBase
{

    /// <summary>Represents the Product field (7887e669-df79-4ba0-b7bb-2c43d6da77c7).</summary>
    //[SitecoreField(FieldName = IProductSelectionConstants.ProductFieldName)]
	[SitecoreField(IProductSelectionConstants.ProductFieldName)]
    Guid Product { get; }

}`

-- Manually generated interface
public partial interface IProductSelection { [SitecoreField(IProductSelectionConstants.ProductFieldName)] IProduct ProductObject { get; } }

-- Manually generated interface for IProduct
public partial interface IProduct : IProductTitle { [SitecoreChildren(InferType = true)] IEnumerable<IProductPricing> ProductPricings { get; set; } }

In this example, ProductObject might be null where Product is not. The behavior seems inconsistent, but even if ProductObject is not null, its children doesn't get populated correctly (ProductPricings)
