Description

1. What is the reason for the change?

Manual testing steps

1. On this branch
2. If you have a zero Staked ETH balance, you should see no Staked Ethereum asset on the homepage or on the ETH asset detail page after clicking the ETH asset on homepage.
3. If you do have Staked ETH already, then you should see that ETH on the homepage and on the ETH asset detail page as well. Unstake Max ETH and wait for transaction to confirm. When you check homepage and ETH asset detail page, there should be no Staked Ethereum listed as balance is now 0.
