Fix dirty cache after failed arweave upload or warp tx

[7i7o]

Cached git remote remained in an inconsistent state after upload to arweave failed or after a failed update to warp

This PR fixes it by cleaning the cached remotes after an unsuccessful push to protocol.land

How to test

• Clone the repo
• Build
• create a symlink to dist/index.js with the name proland-test and add that to your PATH
• use proland-test://[repo-id] as remote to clone git command (remember to set up your wallet path in the git config)
• verify that the folder that caches the arweave txId inside .git/.protocol.land/ exists after git pull or git clone
• try to push a big file from a wallet with no funds to ensure arweave upload fails and check the new messages
• verify that the folder that caches the arweave txId inside .git/.protocol.land/ is removed
