Unable to startup: account alraedy exists

[kornpow]

I have recently recovered a Pool account and was attempting to fund it.
I think I attempted to fund it once (pool account new), but had no balance in my Lightning node, so I added coins to my node and attempting the funding process again, pool account new.

It gave me an error saying that a funding event was already in progress. Which I then looked at using CLI

{
	"accounts": [
		{
			"trader_key": "{my_trader_key}",
			"outpoint": "0000000000000000000000000000000000000000000000000000000000000000:0",
			"value": 10000000,
			"available_balance": 10000000,
			"expiration_height": 745017,
			"state": "PENDING_OPEN",
			"latest_txid": "0000000000000000000000000000000000000000000000000000000000000000"
		}
	]
}

I thought it was weird, so I stopped pool, and restarted and then this error started to occur, preventing me from starting the daemon.

rpc error: code = Unknown desc = account alraedy exists

Expected behavior

Actual behavior

The daemon does not start up

Discussed offline. Connected lnd node was restored as well and is at account key 0. We need to update the account recovery to bump the account key derivation index to at least the last recovered account's ID.
