Multiplayer results don't return scores of users which did not play until the end

[peppy]

Unlike playlists, it's an expectation that users which dropped out still have their scores shown on the results screen.

Currently, rooms/{roomId}/playlist/{playlistItemId}/scores/users/{userId} doesn't return any scores which were not pass.

Have briefly discussed why this occurs with @nanaya (querying is done via multiplayer_scores_high which doesn't contain rows for non-passing plays) but needs a bit of thought as to the best way to resolve. Potentially inserting rows into that table for non-pass plays.
