    Fix race condition in stack listing

    When listing stacks, we first load them from the database, and then we
    load their template in a different transaction. If a stack is deleted in
    the mean time, loading the template will raise a NotFound exception, and
    will make the listing returns NotFound, instead of ignoring that stack.
    This patch handles the exception and continue to try to load stacks.
