Do not use TabModel inside BlockedPopupInfo handler block.

BlockedPopupInfo handler block will be folded into BlockedPopupHandler
which does not have access to TabModel.

Calling updateSnapshotWithOverlay:visibleFrameOnly: is unnecessary,
because it is called from TabInfoBarObserver::OnInfoBarRemoved.

Opening popup functionality was moved to
WebStateDelegate::OpenURLFromWebState, which is currently BVC.
