Previosuly, 404 errors showed a generic error message, making it unclear what could have gone wrong. For security reasons, we don't want people to know if the group does not exist or if the group exists but the user does not have permission. This change updates the error message to reflect both of these possibilities. Bug: Issue 8252 Change-Id: I6940d53b342a81ca10ec78977de4ec548fd10a6f
