job_dispatching.py does not update the Redis Database

[MBus123]

I was trying to create my own redis database while investigating a set of apps. But apparently dex_extractor.py won't store anything. It looks like the catch_a_class() method from PackageNodeList is the problem. It stores data while iterating over the pn_list. But this cannot happen, since the pn_list is initialized as an empty list.
