There was two things very wrong:
- Access of the global aerc pointer before it was initialized.
- The host field of AccountView was left there and still accessed but
never initialized.
Replace the global aerc pointer with a real struct value. Update code
accordingly.
Remove the AccountView.host field which is now useless.
