Fixed error in network node remapping when node gets removed during that remapping operation.
E.g. file systems automatically connected together with the main component, as in the internet card. This should fix a potential crash with OC conduits in EnderIO. Also, unit tests \o/ You'll need ScalaTest and Mockito to run them.
