Transactions - fix doorkeeper feed story error

Summary: missing a setHandles on this codepath I think...? Fixes T6300.

Test Plan: not actually tested - I just think this is the fix since the other renderX methods all do this setHandles thing and I can't figure out how handles get set otherwise...
