IP address not declared soon enough when DivertTraffic: No

[thejoelpatrol]

OS: Ubuntu 20.04
Python: 3.8.10
VM: VMWare Workstation 16
Latest commit: ac33a70
Steps to reproduce:

1. Edit config to set DivertTraffic: No
2. Launch Fakenet

This can be fixed by moving this to line 139:

flare-fakenet-ng/fakenet/fakenet.py

Line 158 in ac33a70

fn_addr = '0.0.0.0'

Note that the same bug also reproduces on Windows with an older version of Fakenet on Python 2.7, I just happened to trigger it on Ubuntu
