Bugfix member months grain

[davidshimamoto]

Describe your changes

member_months breaks when a person with multiple plan memberships is fed into the input layer eligibility file. Because member_id is part of the model, this results in multiple rows per person_id. To fix this, I nulled out member_id, and applied an aggregate to the eligibility data as it's staged for member months to get it to the correct grain.

How has this been tested?

Ran the model with synthetic data that simulates the problem.

Reviewer focus

Note that tuva_last_run has been omitted, but this field is not used anywhere, so it was not needed.
