No email notification for `Space disabled` and `Space deleted` event

## Describe the bug
Currently, email notification for `Space disabled` and `Space deleted` events is not implemented. So, there's no email notification when a shared space is disabled and deleted. And we currently don't know if it will be implemented or not in the near future.


## Steps to reproduce
1. Run the server with email service [mailpit](https://owncloud.dev/ocis/development/testing/#running-test-suite-with-email-service-email).
2. As user `demo` who is a space admin, create a space `toShare` and share it to user `alex`.
3. As user `demo`, disable the space `toShare`
4. As user `demo`, delete the space `toShare`
5. Check emails for `alex` in mailpit.

## Expected behavior
Expected to get email notifications related to `Space disabled` and `Space deleted` ❓

## Actual behavior
Only one email related to space shared is available.
`demo has invited you to join "toShare".`
