SetupAllProperties does not setup write-only properties

[ishimko]

Opening a new issue as per #826 (comment).

Steps to reproduce

public abstract class WriteOnlyProperty
{
   public abstract string Test { set; }
}

[Fact]
public void Write_only_property_should_be_ignored_by_SetupAllProperties()
{
   var mock = new Mock<WriteOnlyProperty>(MockBehavior.Strict);
   mock.SetupAllProperties();
	
   mock.Object.Test = "test";
}

Expected behavior
Test is passed, writing to Test property is ignored.

Actual behavior
Exception is thrown:

Moq.MockException : WriteOnlyProperty.Test = "test" invocation failed with mock behavior Strict.
All invocations on the mock must have a corresponding setup.

Assuming that changing the current behavior won't break any existing tests, I'm all for fixing this. Please feel free to submit a PR.
