Test Scenarios

Steps to Reproduce

• setup a @listen for a on_raw_gateway_event
• create a new voice channel (to ensure no invite has been created for it yet) in a guild with the bot
• give the bot admin perms (i dont know the specific perm that enables bots to view invites, but admin provides all)
• start a voice chat activity and right click on the voice chat in the sidebar and choose 'invite to join '
• view the error appear when this patch isn't applied!
