Hmm, not quite sure how to best fix this in a robust way... We can certainly null check client in trackStores, but then other bits of MatrixClientPeg.assign would error instead. Somehow, we need to signal that the client was destroyed and assign should abort early.

I highly doubt we'll be able to fix this 2-3 years later. Closing until it happens again.
