Investigate stCELO "withdrawal" bug

Copy/pasting bug report from Daniel on Slack

I am getting an error when I try to unstake on stCelo. I get a:

eth_signTransaction: Gas must be provided to sign a transaction

I do have CELO to pay for gas.
this is a screenshot from the console:

we reviewed this error with @therealharpaljadeja and concluded it might be a FrontEnd Issue. @therealharpaljadeja also noticed that the contracts are not verified on Celoscan

This might be caused by a known bug in the stcelo bot. The bug leads to failed activate, claim, and vote operations and occurs when there is a race condition in the bot. It looks like this race condition is becoming more frequent with more traffic.

This seems like problem with wallet or UI, since st-celo bot bug cause only the api call to revert but this looks like revert of original transaction in user's wallet.

Copy/pasting follow-up questions from Slack for context:

I am using a Ledger Nano S and Celo Terminal. I connect it using Wallet Connect.

I am using Chrome

By the way something else odd is happening, one I connect with Wallet Connect and disconnect I am unable to do it again on the same browser account. When I try to connect again and click on Wallet Connect it doesn't show the QR code modal.

update: The contract was verified on CeloScan,
@therealharpaljadeja and I tried to use the withdraw function and got the same error. We now think this is a Celo Terminal issue.

@therealharpaljadeja: If you think this problem originates in Celo Terminal, have you reached out to @zviadm in zviadm/celoterminal yet?
