fix(editor): add and remove categories from events

[st3iny]

Fix #5785

An artifact of the nextcloud-vue migration.

The component is not used anywhere else besides the category select so this is a safe change.

/backport to stable4.7

How can I handle this information? I´m using Nextcloud with docker-compose. Did I have to change the PropertySelectMultiple.vue ? Where can I find this file? It would be great if someone could help me out here. Thanks!

Patching the frontend is not supported. You have to wait until the next release for the fix which should be 4.7.3.
