Fix incorrect value checked for determining moderator

Browse source 
The public instance will be updated with this fix immediately.
This fixes cases in which those with moderator roles are unable
to use mod-only commands as intended.
It also fixes a dangerous bug in which users with the birthday role
assigned to them have unrestricted access to moderator commands.
