RCTCameraRollManager: fix "all" photos filter

Summary: Currently, trying to fetch "all" photos will loop and never complete. Now it appears to produce the expected results (acting like the "All Photos" smart library in Photos) and doesn't loop. Confirmed console log results, showing no loops: P60994983
