Submitting a PayForData tx from the cli fails the first time using the --gas-prices flag

[evan-forbes]

The cli sub command fails when attempting to submit a pay for data transaction while using the --gas-prices flag. This can be recreated in the cli integration test and when using the latest version of master locally using the single-node.sh script located in contrib.

the input is

celestia-appd tx payment payForData "fffffffffffffffe" "68656c6c6f" --chain-id test --gas-prices "0.1uceles" --keyring-backend test --from=celes10824aaey7mc7ut4lgc8hpsqf6c37572ftzn9v5 --broadcast-mode block

the error returned is

raw_log: 'signature verification failed; please verify account number (0) and chain-id
  (test): unauthorized'

just to update on what I found today:

I no longer think that this is caused by adding specific flags, as the same command will create, sign, and broadcast a transaction just fine if ran again. It's only the first time that the transaction is ran do we get the error above.

The account number and chain-id that are being used as input to create a transaction are also what should be expected.

fwiw, this same error occurs with the #399 branch that updates the cosmos-sdk to v0.46.0
