[Bug]: files_trashbin logged NotFoundException /USERNAME/files_trashbin Error while expiring trashbin for user USERNAME

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

From a completely clean developmental install of NC master branch. The only user on the system is currently named admin.

NotFoundException /admin/files_trashbin - Error while expiring trashbin for user admin.

This reoccurs every 35 minutes so it's from a cronjob. It is possible that this stems from my 'trashbin_retention_obligation' => '10, 2' entry in config.php.

Steps to reproduce

1. Fresh install
2. Add entry for 'trashbin_retention_obligation' => '10, 2' to config.php
3. Error eventually occurs from the cronjob and every 35 minutes after.

Expected behavior

No error should be logged because files_trashbin should have been created already.

Additional info

In my NC data folder under the user admin, the directory files_trashbin is, in fact, missing so it would appear the whatever the scheduled job that goes off every 35 minutes is looking for the non-existent files_trashbin directory that somehow wasn't created during server setup.

If I upload a file to NC and then proceed to delete it, the files_trashbin directory is created and the error stops.

Seeing the same but without any manual changes to config.php
And any newly created user creates the same error message.

Same here on NC 34.0 (stable)
