hotspots add transaction requires multiple attempts

[jthiller]

Onboard transaction appears to fail although the necessary transactions are being submitted/processing.

In this example, the onboard transaction reports the successful transaction on third submission.

➜ helium-wallet hotspots add iot Cqa...ay0 --commit
Wallet Password: [hidden]
Error: solana: AccountNotFound: pubkey=6Ld...Vq7

Caused by:

  "result": "ok",
  "txid": "usC...9sN"
}

Perhaps we can add checks for account creation before reporting error?
