removed events_listener; added basic test for webhooks_listener (#348)

Starting with Nextcloud 30 there is a `webhooks_listener` app that is
enabled by default and supports both regular requests and requests from
ExApps!

It has much more and better functionality than `events_listener` in
AppAPI, and we will remove `events_listener` for Nextcloud 32 from
AppAPI.
