EMail Notification change & conflicting HTML ID attribute?

[EngelPika32]

Related issue (with images) for activity-app: nextcloud/activity#897

Steps to reproduce

Updated from NC22 (latest patch) to NC23 (latest patch).

Since that update an additional option appeared under settings/user/notifications. [The top one from the images.]

Expected behaviour

No un-asked e-mail notification.
I dunno what these "unhandled notifications" are, but I never asked to receive E-Mails for stuff I've selected "push" for.

Additionally, I don't see any admin option about this to set defaults.

Actual behaviour

Un-asked e-mail notification from (apparently) a new option.
The HTML code includes ID conflicts (more than one element with the same ID).

---

PR adding the new option: #1074
File (in notifications): src/views/UserSettings.vue:30
File (in activity): templates/settings/form.php:73

One of these has to change their ID.

Great find. Let's adjust it in this app, as the activity app got some rework and migration to another JS code base in the meantime, so backporting there is much harder
