Steps to reproduce

1. Create a groupfolder with trailing whitespace using the occ command and a subfolder: sudo -u www-data php /var/www/nextcloud/occ groupfolders:create "Test folder " and then sudo -u www-data php /var/www/nextcloud/occ groupfolders:create "Test folder/Test Subfolder"
2. Observe that the folders do not nest properly:

3. Observe that the trailing whitespace is visible in the Web GUI once the folder name is being edited:

Expected behaviour

Whitespace at the end or beginning of a folder name is automatically trimmed when the group folder is created as per: https://github.com/nextcloud/groupfolders/issues/2990

Actual behaviour

The trailing whitespace is not trimmed leading to issues with nesting

Start with the occ groupfolders:create command and compare its handling of leading and trailing whitespace with the behavior described in issue #2990. Reproduce the nested-folder case, then verify that created group folder names are trimmed and that the subfolder appears under the intended parent in the Web GUI.
