Empty specify() and describe() blocks pass tests

[mcampo-wework]

The documentation states that specify() and describe() calls that don't pass anything to $fn will be marked as incomplete, but when I run them they are marked OK. These tests should either fail or be marked as risky to ensure that at least some assertions are being made.

$this->specify('some test');

CLI output:
