pool: UI allows double account creation and isn't aware of multiple accounts #274
Description
Today it's possible for a user to accidentally create an account twice by clicking the "Fund Account" button in short succession. The end state is that the user has two accounts, but only one fo them show up in the UI, as the UI currently assumes there's only a single account for a given user (though it's possible to create multiple).
Expected behavior
Fund Account button is greyed out and unable to be clicked while funding in process.
UI shows balance across all accounts (with a sort of toggle?).
Actual behavior
Account able to create twice in quick succession.
Only first account is shown in the UI.
