Subject: Better support for autoclonetype of nested Bundles (#769)

* Better support for autoclonetype of nested Bundles

* Move bundleStack to dynamicContext

* prefer $outer if available, make guesses distinct

* Catch IllegalAccessException in autoclonetype
In strange circumstances this type of exception can occur when accessing $outer
