Update DataChannelControllerTests to exercise teardown path.

This updates DataChannelControllerTests to shut down the DCC in the
same way it's shut down by the owning PeerConnection instance:

* Call TeardownDataChannelTransport_n()
* Call PrepareForShutdown()

Also calling PrepareForShutdown() from PC's dtor to be consistent with
how `sdp_handler_->PrepareForShutdown()` is called since it appears
that many tests do not call PC::Close() before destruction.
