Connect sidechain pins when adding sidechain [ports]

Browse Source 
This is in preparation to allow to skip adding sidechain ports
by default. When a user later adds the SC input ports, it is
convenient to connect the pins just like they are when they
are connected when instantiating the plugin (via reset_map).
