Calling Janitor:Destroy() does not always work

[MiaGobble]

This is a critical issue that keeps me from completely relying on this library.

Consider this code snippet:

local This = Janitor.new()

This:Add(RunService.Heartbeat:Connect(function()
	--...
end))

This:Add(function()
	--...
end)

This:Destroy()

In this example, there is a chance that nothing in the janitor is cleaned up when I call Destroy(). This means the connections aren't cleaned up, functions aren't called, etc. Swapping to an equivalent library, such as Maid, fixes this issue.

This seems to happen more if I attempt to destroy the janitor within a second or less of creating it.

Again, this is a critical issue, and keeps happening for me in important situations. I can't rely on this library until this is fixed.
