Extend ExcludeDefaultValues to ignore empty strings

There’s no JS configuration that lets you configure this behavior, the only 2 generic solutions I can think of is similar to @daleholborow link of registering a Response Filter that uses reflection to generically go through each property and replace each empty string with null.

The other solution is to add a ShouldSerialize() API on POCOs you want this behavior on to ignore any string properties with null or empty values, e.g:

public class Poco {
  public bool? ShouldSerialize(string name) => this.IgnoreEmptyStrings(name);
}

public static class MyExt
{
    public static bool? IgnoreEmptyStrings<T>(this T obj, string name)
    {
        var accessor = TypeProperties.Get(typeof(T)).GetAccessor(name);
        return accessor?.PropertyInfo.PropertyType == typeof(string)
            ? !string.IsNullOrEmpty((string)accessor.PublicGetter(this))
            : (bool?)null;
    }
}
