Fix cli profile mode loading
This MR fixes a small bug that caused the selection of incorrect lighting modes when loading a profile in cli mode. Loading profiles from the gui was not affected.
After loading the profile OpenRGB checks for the "--mode" command line argument. If absent the desired mode for each rgb controller was mistakenly set to false (=0) instead of leaving it unchanged.
Steps to reproduce:
- Create a profile with an active mode which isn't the first mode for the controller.
- Start OpenRGB with "-p Profile".
- Lights should switch to the desired mode for a moment, then back to the first mode.
