Sync simple linked lists (#295)

This updates the exercise to sync the canonical test data.
Note, this change also attempts to maintain support for solutions
written before the canonical data was added. The test differs from
the canonical data in the following ways:
- len property is used in place of a dedicated count() function
- to_array is used in place of to_list
- to_array is used for validation in the reverse tests
