Background image on hero background Element type throws error when rendered

[PeeDeeWhite]

If you select a background image for the hero element then you get the error

ArgumentNullException: Value cannot be null. (Parameter 'mediaWithCrops')

This is because the hero.cshtml partial is trying to find the 'image' property instead of 'background' image

var backgroundImage = Model.HasValue("backgroundImage") ? $"background-image:url({Model.Value<MediaWithCrops>("Image").GetCropUrl("hero")}); background-repeat: no-repeat; background-size: cover;" : string.Empty;

The product page also has this problem.

I will submit a fix for this shortly
