[orca] Web: Don't speak contents if new focus has died and focus event queued

[Joanmarie Diggs <joanied src gnome org>]

commit 6f6bdacd1dec1524101d971a1ba55c6dc1e0303c

    Web: Don't speak contents if new focus has died and focus event queued
    
    If the newly-focused object gets destroyed during line contents
    generation, and if we have a new focus event, return early. This
    should hopefully reduce some chattiness as well as some broken
    presentation (e.g. if the destroyed object is in the middle of valid
    objects)
