Properly detect the end of an instant-cast spell cast on yourself.

Properly detect the end of an instant-cast spell cast on yourself.

Treat friendly spells cast on a target of yourself the same as a spellcast
that procs a buff on the player -- we track the buff appearing on the
player and remove the spell from the in-flight spell queue.
