Ensure recursive validation won't follow static properties

[myarichuk]

1. At the moment, for an object with the following structure the validation will throw StackOverflowException. The pull request ensures that recursive validation won't follow static properties.

public class FooBar
{
  //some properties...
  public static FooBar Default { get; } = new FooBar();
}

2. Also, it is possible to have deep enough object to cause StackOverflowException. The pull request ensures the recursion will throw if it goes deeper than 100 levels
