Uninstall script doesn't remove group

[Couto]

Running the uninstall script with sudo python3 uninstall.py. Everything was reported as successful, however the group anudeepND/whitelist was not removed from PiHole, nor is it possible to remove it manually. Although the Web UI reports success after an attempt to remove it, if we refresh the browser, the group is still there.

While I haven't investigated, I have the feeling that this is somewhat related to #187

My fix was to remove it directly from gravity.db with DELETE FROM "group" WHERE id = 2552552551;

@Couto Thanks for reporting the issue, I have reverted the PR for now. I will update the script as soon as possible.

Thank you a lot for the quick response, and a special thank you for maintaining this project! <3

If anyone wants to remove the group, you can run this command in the terminal:

sqlite3 /etc/pihole/gravity.db "DELETE FROM 'group' WHERE id = 2552552551;"
