Describe the bug
I can't uninstall cake-qos

To Reproduce
Steps to reproduce the behavior:

1. Fresh firmware reset
2. Do the install via mkdir -p /jffs/addons/cake-qos && /usr/sbin/curl -s "https://raw.githubusercontent.com/ttgapers/cakeqos-merlin/master/cake-qos.sh" -o "/jffs/addons/cake-qos/cake-qos" && chmod 755 /jffs/addons/cake-qos/cake-qos && sh /jffs/addons/cake-qos/cake-qos install as instructed
3. Cake-Qos tab active and working
4. Run command cake-qos uninstall
5. Terminal states no such thing exists

Expected behavior
The tab would be removed

Connect to your router via SSH and type cake-qos to display an interactive menu which "uninstall" is the 4th option. Type 4 on that screen and hit enter.
