BindableLayout.SetEmptyViewTemplate sets EmptyView instead of EmptyViewTemplate

[VincentH-Net]

Xamarin.Forms/Xamarin.Forms.Core/BindableLayout.cs

Lines 78 to 81 in 2cb4c54

	public static void SetEmptyViewTemplate(BindableObject b, DataTemplate value)
	{
	b.SetValue(EmptyViewProperty, value);
	}

A single statement change would fix this:
b.SetValue(EmptyViewProperty, value); -> b.SetValue(EmptyViewTemplateProperty, value);

Possibly this also fixes #9905, #12374 and #10831

This issue was first reported in #11428 and again in #12623 (comment)
