Did we really not have an issue for this?

Proposed Changes

Fix the test

Additional Info

The test was failing likely due to it running on two nodes, and in some cases when a message creating a channel landed on one node, we'd query state from the other node - which isn't the block miner, and could fall behind in sync (block time was 5ms, so that could happen quite easily). The fix is to wait for the nodes to be in sync at certain points.

I think this makes sense, though I don't know for certain this was the cause of (some of) the flakiness. I suspect a similar pattern might cause flakiness in other tests too.

head, err := paymentReceiver.ChainHead(ctx)
require.NoError(t, err)

paymentReceiver.WaitTillChain(ctx, kit.HeightAtLeast(head.Height()))

I'd even suggest doing head + 5 here, just in case of minor reorgs.

There's one miner in that test, can't have reorgs
