Fund account/Trustline to allow accepting connected wallet

[jeesunikim]

Quick feedback on the "fund account" screen in lab: we have an option to log in with a wallet, but after we log in it still requires us to add the public key in order to add a trustline or fund the wallet again. i feel like that part shouldn't be necessary if you are already logged in with a wallet unless I am missing something.

from slack.

@minkyeongshin we have this in design. Let's think about including a connected wallet address when you return.

@minkyeongshin @jeesunikim How about adding the dropdown list including the connected wallet as well as other saved wallets?
