Move helper functions for influence tests to be under helpers directory (#1260)

Summary:

As titled. 

This changes helps keeping the tests to be an exact mapped of the implementations.
A future follow up could be a consolidation of helpers. (there could be some helpers universal for both attribution and influence)
