Update Kivan Quest dialogs

Jozzi (sea snake) was not disappearing after final conversation with
Keth.  Appears to have been due to DestroySelf() command to Jozzi being
after EscapeArea() command to Keth.  As per note from Yovaneth,
commands following EscapeArea don’t run.  Reordered final action to
place EscapeArea command last.
