SetupProperty fails if property getter and setter are not both defined in mocked type

[stakx]

This is basically #886 again, which was fixed for SetupAllProperties but not for SetupProperty.

Reproduction code:

public class Base
{
    public virtual object P { get; set; }
}

public class Derived : Base
{
    public override object P { get => base.P; }
}

var mock = new Mock<Derived>();
mock.SetupProperty(m => m.P);

Actual behavior:

The call to SetupProperty throws this exception:

System.ArgumentException: Expression must be writeable
Parameter name: left
   at System.Linq.Expressions.Expression.RequiresCanWrite(Expression expression, String paramName)
   at System.Linq.Expressions.Expression.Assign(Expression left, Expression right)

   at Moq.Mock`1.SetupProperty[TProperty](Expression`1 property) in …\src\Moq\Mock.Generic.cs:line 616

Expected behavior:

The call to SetupProperty should succeed because Derived.P is both readable and writable.
