Update to version 0.1.3.4

[chinganc]

Fix multiple bugs

1. Sometimes TraceGraph does not follow heap ordering.
2. When @Bundle(trainable=True) is applied to a class method, different class instances will unintentionally share the same parameter.
3. When calling @Bundle class method(s) multiple times of a class instance, duplicated nodes of the class instance are created, which all point to the same class instance.
4. When accessing the bundled method of a class instance, it returns a partial function instead of FunModule, which makes accessing properties of the bundled method difficult.
