Pholio - fix show older transactions for if there are inline comments

Summary: We didn't load enough data for this case for the custom view class Pholio uses. Fixes T6770. Re-jiggers the signature of the loadImages function in the PholioMockQuery to get there so as to not duplicate any business logic.

Test Plan: made a pholio mock with lots of inline comments. pre-patch "show older" fatals and post-patch "show older" works
