cli config can't read current values

Created by: tomyri

I can't read current values in console, but I can set them if I use exact values. But for DPI, higher or lower doesn't change anything. GUI seems to read the value right.

tomi@ArchAlly ~> solaar config 1 Performance Mouse MX (Performance MX) [101A:8D4A1FDC]

Sensitivity (DPI) solaar: error: 'NoneType' object has no attribute 'replace'
