Fix PersistableBundle C++ -> Java interop

PersistableBundle.java expects items to be sorted by the hash codes
of the keys, but PersistableBundle.cpp isn't compatible to it.

PersistableBundle.java now knowns what was parceled by C++
because it now uses a different magic, and change the unpercel
strategy.
