Network module: no received/transmitted bytes with interface auto-select

[ppascher]

Sinc commit 0a48413 my network module did not show received/transmitted bytes anymore using interface auto-detection. Manually setting my interface name in the config fixes this.

cat /proc/net/dev

I tried to add a spdlog output (in modules/network.cpp after iss >> r;) to show me received bytes for each interface during each interval but it would not print anything with auto selection. It only got executed after manually setting my config "interface" value to "enp5s0".
