Fix account injection bug

It seems `selectedAddress` was removed from the keyring-controller’s state, and is used to populate the injected current account.

I couldn't help myself, I dug around, I found a PR named [changed all instances of selectedAddress to selectedAccount](f5b0795ac5) by @Zanibas.  Sorry, Kevin!  Had you actually changed all instances, this bug would not have happened.

Fixes #908
