RS Bridge causes Java NullPointerException when no Refined Storage network is attached

[Havaro]

Descripe

Executing a lua function for the Rs Bridge peripheral without any Refined Storage network attached to it throws a java.lang.NullPointerException. Additionally, an error is thrown in the minecraft logs.

Expected behaviour is to return simply nil, possibly with a warning. The NullPointerException should not be shown in the server logs, but be catched.

Problem has been experienced on a server, not tested in singleplayer.

Steps to reproduce

1. Place a computer next to an Rs Bridge, do not connect an Refined Storage network;
2. Start the computer with an interactive lua prompt;
3. Wrap the Rs Bridge as peripheral;
4. Use any Refined-Storage-interfacing command, such as listItems();
5. A java.lang.NullPointerException is thrown.

For 1.18 - I'll just return nil/0 if the network is not connected I'll refactor this in 1.19/0.8. The result would then be false, "Network not connected"/true, 63(As example) or something similar.
