Exception on Network creation: Initial server in a new network created twice, once each by quassel-webserver directly and by node-libquassel

See:

• https://github.com/magne4000/node-libquassel/blob/master/src/request.js#L506
• https://github.com/magne4000/quassel-webserver/blob/master/public/javascripts/angular-controller.js#L704

The end result is that on creating a new network, the ServerList contains an array of two "servers":

• [0] with the settings just created, and most fields including numerics such as ProxyPort set to the empty string (the server quassel-webserver created)
• [1] with an undefined hostname (throwing an exception and aborting the process) and fields set to the node-libquassel defaults such as ProxyPort set to 8080 (the server node-libquassel created)
