In Jabu Jabu MQ, when entering the Big Octorok's room, the minimap would randomly display chest icons even though that room has no chests. This behavior was due to a authentically missing minimap mark entry for this room in MQ (the last room in the dungeon) from decomp. Because of the missing entry, N64 hardware would OOB read the next map mark data which just happens to be Forest Temple MQ room 0 (which has no chests). In SoH, however, the OOB read would behave differently, leading to garbage data being read.

This PR adds the 17th entry for Jabu MQ's minimap, matching Jabu Vanilla's minimap entries, indicating there are no chests for this room.

Fixes #1882
