Force background state update after removing an account (#7840)

The e2e tests were failing intermittently after removing an account
because the account was shown as not deleted after the removal. I
suspect this was because the account _had_ been removed, but that
change to the background state hadn't yet propagated to the UI.

The background state is now synced before the loading overlay for
removing the account is removed, ensuring that the removed account
cannot be seen in the UI after removal.
