Visibility Issues With `protected internal` Property

[JasonBock]

To reproduce:

public abstract class VisibilityIssues
{
  protected internal virtual bool OwnsHandle { get; protected set; }
}

var expectations = Rock.Create<VisibilityIssues>();

This causes errors like:

Error - Id: CS0273, Description: Rocks\Rocks.RockCreateGenerator\SKRegion_Rock_Create.g.cs(268,15): error CS0273: The accessibility modifier of the 'CreateExpectationsOfSKRegionExtensions.RockSKRegion.OwnsHandle.set' accessor must be more restrictive than the property or indexer 'CreateExpectationsOfSKRegionExtensions.RockSKRegion.OwnsHandle'

Basically, the property is generated as protected, not protected internal, so when the setter is generated as protected set, it causes an issue.
