LocalStorageWrapper has racing condtion

[stanleyyconsensys]

Description:
when connecting a wallet, it will set the wallet id into Storage,
when setting a item in Storage, it will generate a UUID as key and delete the previous item with the previous key

however, if we try to get the storage in async way, e.g put getLastConnectedWallet in reactjs useEffect

the behaviour will become a racing condition, new item may appended to the storage

it could result when getting last wallet id incorrect

resolution:
may try to use https://www.npmjs.com/package/async-mutex to create lock
