Fix occasional logout failure

It seems a dialog sometimes appears asking if you want to lose
changes (even though we have no changes; it seems based on timers in
some way). Playwright defaults to dismissing them (so quickly you might
not even see them) so accepting instead fixes navigation to the logout
page getting canceled.
