Reduce ConnectionManager to a ConnectionMap

createConnectionMap$ now returns the behavior of connections and their
participants directly and takes an already resolved local transport
instead of an observable of it. The CallViewModel wraps it with mapScoped
so that a new map is built, in a fresh scope, whenever the local transport
changes, and swallows local transport errors there since the local member
already surfaces them in the UI.
