81e5357e62 fix handling of Rabin-like input for dnf_to_dca()
The bug is mentioned by Maximilien Colange in a comment to issue #317,
but turned out to be unrelated to that original issue.

between the created states an the DNF clause in a named property.

property.

property.  Relying on seen marks and trying to deduce the matching
original clause could only work from plain Rabin.
