[wcf] make /js and /jsdebug dispatchers work.

There were several issues here:

- The IChannelDispatcherBoundListener was defined twice, in two different namespaces, and it caused code in
  ChannelDispatcher.Attach not to set its associated listener's ChannelDispatcher property to the correct value.
  This, in turn, caused incorrect HttpListenerManagerTable operation, where it would put the "/js" and "/jsdebug"
  dispatchers in separate HttpListenerManagers, instead of in the main (base) service's one.
- After fixing the above, it turned out that SvcHttpHandler selected the manager based on the host's base address,
  when it should first try to find one whose URL matches the current request exactly.
