Allow fragment arguments to get marshaled properly

[SeppahBaws]

This PR fixes a bug I was having, where list operations on a list inside of a fragment with arguments caused the fragment's store data to be set to null.

Apparently the fragment's arguments never got marshaled, so in the fragment store the variables was an empty object, and thus the lists in the fragment never got added to the cache's lists collection.

@AlecAivazis I was not entirely sure how to write a proper test case for this, some help with writing one would be appreciated :)
