fix(operation): groupfolder path is user independent

getPath returns the relativ to the user, i.e.
$userid/files/$groupFolderInternalPath which is then used to contstruct
the absolute path and keeping this information. By using getInernalPath()
we only receive the groupfolder relativ path and can construct the correct
and expected Nextcloud relative path as advertised.
