If the owner is dead, emit "owner_died" instead of "owner_unset".

* evolution-shell-component.c (impl_setOwner): If the owner is
dead, emit "owner_died" instead of "owner_unset".
(impl_owner_died): New, default implementation for "owner_died".
(class_init): Install it.

* evolution-shell-component.h: New signal "owner_died".
