Fix Errors on run build

Currently we have 2 errors happening on npm run build

./components/account/AccountBalanceCard.tsx 91:6 Warning: React Hook useEffect has unnecessary dependencies: 'cardNameMap' and 'grabNumericValue'. Either exclude them or remove the dependency array. Outer scope values like 'cardNameMap' aren't valid dependencies because mutating them doesn't re-render the component. react-hooks/exhaustive-deps

./components/account/AccountWitnessVotesCard.tsx 91:6 Warning: React Hook useEffect has a missing dependency: 'fetchWitnessVotes'. Either include it or remove the dependency array. react-hooks/exhaustive-deps
