Bug: Review requests not dismissed when required reviews satisfied

NOTE: Heavily edited from original Issue submission (see Edits)

When an file has an OR rule for multiple codeowner groups, the system does not dismiss unneeded reviewer groups when one of the codeowners groups is satisfied.

1. File 1 requires team A or B to approve
2. A member of team A approves, satisfying the required reviews for File 1
3. Team B still requested for review

Expected Behavior:
Since the rule A or B is satisfied by A approval, the requested review for B is no longer necessary, and ought to be dismissed

Actual Behavior:
The system keeps the review request for group B active, even though it's already been satisfied.
