How to recreate this issue:

- Have 2 servers connected properly for interserver networks
- Create one custom portal in each server in the network centre
- Change the default network name to centre in server 1
- Try go to the other portal in the other server

There will be a conflict with the custom centre network and a default network, therefore prompting the centre network to change names to centre1. This modification is not sent to the other server 2.

What needs to be done is to add bungee protocol messages for to accommodate for any renaming of networks and portals.

I think I fixed this in commit 5a6a2e2
