Don't be strict about solutions

If expected.sku exists, check that the solution matches it, otherwise,
just rely on the solution having been some unknown solution, so long
as it did not modify the pre-set tiles for the problem, and is a valid
and complete sudoku board. This opens up the possibility for testing
multi-solution puzzles.
