Prevent showing connected accounts without origin (#8891)

There was a case where the `activeTab.origin` was not set, yet the user
could still navigate to the "Connected accounts" modal, which assumes
that `activeTab.origin` is set. This would happen in Firefox when the
user opened the popup on a page internal to Firefox (e.g.
`about:blank`). The connected status indicator would still be shown,
but the UI would crash when it was clicked.

The connected status indicator is now hidden whenever
`activeTab.origin` is falsy. The 'Unconnected account' alert has also
been made impossible to trigger in that circumstance.
