chore: reduce tokenBalances state updates (#5726)

## Explanation

When a user removes an account; tokenBalances controller would still
fetch balances for the tokens and update state.
This was happening because tokensController does not remove tokens from
state when a user removes the account.

This PR cleans up tokens from tokensController state once a user removes
an account.
It also cleans up the balances from state when the user removes the
account.

This PR also adds a check to see if token balances has changed after
fetching them; if none of the balances changed; no need to update state.
