Manual testing steps

1. git checkout Version-v12.11.0, yarn, yarn start
2. Reset your wallet state
3. Permission a dapp with some accounts and chains
4. Open extension console and run await chrome.storage.local.get() to get local state
5. Check local state to ensure that the dapp has eth_accounts and permmitedChains permission AND that there are some subjects that you did not explicitly authorize that have also have permissions, but not eth_accounts permissions (should be just snaps related)
6. git checkout this branch, yarn, yarn start
7. Open extension console and run await chrome.storage.local.get() to get local state
8. Check that your dapp has a endowment:caip25 permission now
