unattended-setup-box: Don't steal input focus from username entry
When users are typing in the Username entry (in the Wizard), we run checks that verify whether all the info required to perform an express installation has already been inputed.
Commit 9746c634 introduced a bug in which the password entry was grabing focus (and consequently stealing it from username entry) for the period when the password entry is empty.
Fixes #347 (closed)
