Fix Rendezvous over BLE after recent changes (project-chip#4012)

PR project-chip#3704 introduced a change that the BLE transport in
RendezvousSession is only initialized when PeerAddress
in RendezvousParams is of type BLE. However, PeerAddress
isn't initialized anywhere. As a result Rendezvous over BLE
stopped working between Android CHIPTool and accessories.

Btw, remove an assert related to the storage delegate
as it seems an optional member of the device controller.
