Fix pack pass check considering converted plays when pack is not associated with a ruleset

[bdach]

Reported privately.

The corresponding web-10 query looks like this (somewhat abridged):

SELECT COUNT(*) FROM (
SELECT p.beatmapset_id FROM osu_beatmappacks_items p JOIN osu_beatmaps b USING (beatmapset_id) JOIN osu_scores_high s USING (beatmap_id) WHERE s.user_id = @userId AND b.playmode = 0 AND pack_id = @packId UNION DISTINCT
SELECT p.beatmapset_id FROM osu_beatmappacks_items p JOIN osu_beatmaps b USING (beatmapset_id) JOIN osu_scores_taiko_high s USING (beatmap_id) WHERE s.user_id = @userId AND b.playmode = 1 AND pack_id = @packId UNION DISTINCT
SELECT p.beatmapset_id FROM osu_beatmappacks_items p JOIN osu_beatmaps b USING (beatmapset_id) JOIN osu_scores_fruits_high s USING (beatmap_id) WHERE s.user_id = @userId AND b.playmode = 2 AND pack_id = @packId UNION DISTINCT
SELECT p.beatmapset_id FROM osu_beatmappacks_items p JOIN osu_beatmaps b USING (beatmapset_id) JOIN osu_scores_mania_high s USING (beatmap_id) WHERE s.user_id =  @userId} AND b.playmode = 3 AND pack_id = @packId) a

If it is not immediately clear why the above disallows converts, then to spell it out: it is the part that the query is split into four UNION'd parts, each of which queries only one scores_high table for each of the rulesets, and only includes the beatmaps in the pack which have the same playmode.

For profiling purposes, here are two examples of query shapes after this change, taken from the test (params may need tweaking appropriately):

SELECT COUNT(distinct p.beatmapset_id)
FROM osu_beatmappacks_items p
JOIN osu_beatmaps b USING (beatmapset_id)
JOIN scores s USING (beatmap_id)
WHERE s.user_id = 2 AND s.passed = 1 AND s.preserve = 1 AND pack_id = 40 AND `s`.`ruleset_id` = `b`.`playmode`

SELECT COUNT(distinct p.beatmapset_id)
FROM osu_beatmappacks_items p
JOIN osu_beatmaps b USING (beatmapset_id)
JOIN scores s USING (beatmap_id)
WHERE s.user_id = 2 AND s.passed = 1 AND s.preserve = 1 AND pack_id = 2036 AND `s`.`ruleset_id` = `b`.`playmode`
