Bug description

An issue has been identified regarding the simultaneous deletion of multiple files from the trashbin in Nextcloud versions stable27, stable28, stable29, and master. When attempting to delete these files concurrently, a performance degradation occurs due to the simultaneous sending of multiple identical requests to the same endpoint.

Steps to reproduce

1. Access Nextcloud and navigate to the trashbin.
2. Select multiple files for deletion.
3. Initiate simultaneous deletion of all selected files.

Expected behavior

We should probably que deletion (and or "empty trash") request when there are too many to handle at once.
