An unhandled promise rejection always happens regardless if it's caught down the line

[ProjectAuroraRBLX]

ISSUE
When attaching a catch after a promise is added to the janitor through Janitor:AddPromise(), it will still throw an unhandled rejection:

local Packages = game.ReplicatedStorage.src.Packages

local Janitor = require(Packages.Janitor)
local Promise = require(Packages.Promise)

local janitor = Janitor.new()

janitor:AddPromise(Promise.new(function(resolve, reject)
	task.wait(2)

	reject("THIS REJECTED")
end)):catch(warn)

FIX
The fix seems to be changing the return in Janitor:AddPromise() to the below:

	-- newPromise:finally(function()
	-- 	if Get(self, uniqueId) == newPromise then
	-- 		Remove(self, uniqueId)
	-- 	end
	-- end)

	-- return newPromise :: never

	return newPromise:finally(function()
		if Get(self, uniqueId) == newPromise then
			Remove(self, uniqueId)
		end
	end)
