Fixes Aggregated Individual Contribution miscalculation

[daltonscharff]

Description

Modifies the getCandidateSummary query to include all contributions where the canon_committee_sboe_id matches the candidate, regardless of whether contributor_id is NULL or not.

Why?

Aggregated individual contributions were not always included in the summary data on the upper right of a candidate's summary page
