Initialize JingleThreadWrapper in the Android client

Initialize JingleThreadWrapper in the Android client

Previously Android client was crashing because JingleThreadWrapper
was not initialized for the networking thread. It was broken by
crrev.com/271351, which removed JingleThreadWrapper initialization
from  LijbingleTransportFactory.
