Setting and deleting storage.id[] values use different keys

[pdehaan]

Randomly looking at /src/index.js, I noticed that when we set the storage.id[*] we set the key as msg.payload, but when we delete the storage.id[*] the key we're using is msg.payload.id. Not sure if it's a bug, or if I'm just misreading...

• /src/index.js:27 says:

  storage.id[msg.payload] = tabs.activeTab;
  

• /src/index.js:35 says:

  delete storage.id[msg.payload.id];
