Points: Fix onboarding error

[benisgold]

Fixes APP-1001

What changed (plus any additional context for devs)

When the user signs in, signPersonalMessage is called. This function calls loadWallet which calls loadAddress. The error was occurring because loadAddress was loading the wrong address. I investigated this, but wasn't able to get to the bottom of it. To circumvent this issue, the user's accountAddress (which is correct) is now passed into a call to loadWallet which is passed into signPersonalMessage.

Ticket for overarching issue:

What to test

To repro on develop:

1. switch to a watched wallet
2. create a new wallet
3. onboard to points
4. error should occur when signing in
