Only opening new tab on dapp request for unitialized wallets

[ryanml]

This adds a proxy to the passed openPopup method for ProviderApprovalController

Provider approval requests will just open the welcome page in a new tab for users who have not onboarded/started MM, and will not attempt to create a notification

Provider approval functions as expected once user has created an account

I think this URL should be chrome://wallet/home.html

@bbondy won't the URL rewrite core-side catch and rewrite it?

MM creates windows/tabs using relative paths

[bbondy]

You can try, I'm ok if it works. I had seen that if you try to load the chrome-extension URL directly it doesn't show the Brave icon and verified brave page, but if you do use the chrome:// URL which shows as brave:// it does. If it works like you have it oh master though, then that's cool.

Updated this to chrome://wallet/home.html, seems that you don't get the brave page items without it, as you said.

One thing to keep in mind is that MM does use the relative path to open windows and views, so this may be something to go through and update across the board as well.
