System.InvalidOperationException: 'This operation is not supported for a relative URI.'

Problem: Serializing an object which has not an absolute URI, just a relative.
Exception thrown: System.InvalidOperationException: 'This operation is not supported for a relative URI.'

Source of the Problem: LiteDB/Client/Mapper/BsonMapper.cs::128

Original:
RegisterType<Uri>(uri => uri.AbsoluteUri, bson => new Uri(bson.AsString));

correct Version should be:
RegisterType<Uri>(uri => uri.IsAbsoluteUri ? uri.AbsoluteUri : uri.ToString(), bson => new Uri(bson.AsString));

Workaround:
manually register the custom mapper like:
BsonMapper.Global.RegisterType<Uri>(uri => uri.IsAbsoluteUri ? uri.AbsoluteUri : uri.ToString(), bson => new Uri(bson.AsString));
