fix: resolve notification issues NOCHANGELOG

Fixes #1981 (closed), #1982 (closed), #2056 (closed) and #2057 (closed)

Workaround for #1981 (closed) is just that. A workaround. For some reason, vuex does not want to trigger a getter update when field from another store is set to null, so I decided to lie about the 'never' button. Technically speaking, it will now schedule the message a 100 years into the future.
