Remove an inappropriate assertion in validation context. spec_to_dsf() should not report invalid input by failing an assertion, because one of the contexts it's called from is validate_desc(), in which the whole point is to present a useful error message to the user before getting to the point where an assertion might go off at all. Game description 5j:c1_5o4_3c,c___aba___cca_a_a_aca now fails validation cleanly, where previously it would trigger this bug.
