Bug description

Situation: My user uses a shared folder "project" from user Sarah. Sarah's user does not have sufficient space.
my user tries to upload files from an android app or desktop app and gets an error message about insufficient space. Sadly, neither the apps nor the nextcloud.log on the server state that the "project" does not count towards the quota by my user. Only when uploading via the web UI the error message names Sarah's account.

Imagine a not too uncommon structure like this, which can add to the confusion which user a folder “belongs to”.

Project
├── Photos
│   ├── lightonflux
│   ├── sarah
│   └── steven12
└── Videos
    ├── lightonflux
    ├── sarah
    └── steven12

Steps to reproduce

1. Create new user A with very little space
2. Share folder from that user A with another user B that has ample space.
3. The user B uploads files until the quota of user A is reached

Expected behavior

The error messages in the log file (nextcloud.log) and all apps should tell which user the storage/folder that has insufficient space belongs to.
