split: demonstrate that discard after more than one commit is misbehaving

The `assert` that this patch removes was introduced in 9242d0b5f74d, when we
didn't have the test that this patch adds. Without the `assert` we can actually
see the incorrect behavior. With it, the test would throw an AssertionError
just before "forgetting c", when hg split is handling the second discard
action.
