[Bug] Librecam not working with multiple user profiles!

**Describe the bug**
When I have multiple users Librecam wants to use /storage/emulated/0

But it should use  /storage/emulated/11 (for user 1)
or  /storage/emulated/12 (for user 2) 

-> So it shows "Permission Denied!" errno = 13

**Other Information:**
 - App version 2.0.1
 - Device: OnePlus 6T
 - OS: Android 13
