[Bug] Contact's age continues to increment after death

[tom22k]

The age of a contact with a death date set continues to increment, and its birthday continues to appear in synced apps (e.g. Right Calendar) after the death date.

the birth day should always be shown. IMOHO
it is still a birthday.
having the death day on a calendar should be optional.
that could be traumatizing for some.
