travis: remove after_success calls
travis: remove after_success calls

Both daemon and demo are being validated separetly and their state is
reported by other script so we don't need to use `after_success`.
Moreover the first will always fail since `ceph-mon` is purge if it
succeeds and then we are processing to the ceph-demo test.
