Registering add-on of same name

Looks like Blender doesn't like it if you register two add-ons of the same name, investigate further what issues can arise and potential fixes

Looks like if you try to register two add-ons generated from node trees with the same name, NodeToPython overwrite all the previously stored information about the old add-on. However, it seems like it tries to run the old operator unless you restart Blender.

Attempts could be made to detect if there are any addons/operators with the same name (https://blenderartists.org/t/how-to-know-if-an-operator-is-registered/638803/2). It seems murkier to try and differentiate between if you're just updating an old add-on, or if there are two separate add-ons that happen to share the same name.

For now, I don't think NodeToPython should try to be responsible for resolving these conflicts, but it's not out of the question for a future release
