Summary of Changes:
This change adds functionality to randomize tx execution for every entry. It does this by implementing OrderedIterator that iterates tx slice as per the order specified. The order is generated randomly for every entry.

* fail deserialize if paths don't work
serialize paths, too
* test that paths are populated from a bank snapshot
