Fixed bug causing snippets to be overwritten. The issue was in

`create_snippet_attribute`. The singleton method was being defined
incorrectly. Specifically it was being defined on the model class
rather than on a singleton class. As a result, it was being overwritten
every time thru `results` loop in `instantiate_results_from_results`.
A very similar issue is nicely described here:
