refactor: Remove call to StartShutdown from qt

Use interfaces::Node object instead.

There is a minor change in behavior in this commit, because the new code calls
InterruptRPC() and StopRPC() when previous code did not do this.  But this
should be a good thing since it makes sense to interrupt RPC when the system is
shutting down, and it is better for the GUI shut down in a consistent way
regardless of how the shutdown is triggered.
