Remove the unreachable scroll-to-top branch from the view tab handler

Web Awesome's tab group never emits wa-tab-show for a click or Enter on the
already-active tab, so the same-view branch in _handleViewSelected has not
been reachable by user input since the migration in #26951. It only fires
for the group's own sync events, and once hui-root binds the group's active
property (#54613) those events also fire when the group is re-created after
leaving a subview or edit mode, overriding the restored scroll position.
