[evolution-patches] patch for crash in alarm daemon

[Rodrigo Moya <rodrigo novell com>]

yesterday, when using only the system tray for testing my fix for
#62030, found a crash happening when you dismiss an alarm from the
system tray icons menu, and then remove later that event. It crashed
because the on_dialog_objs_removed_cb was still being called. This fixes
that.
