Five Options files seeded their tab tables with { ... } instead of {}.
At chunk scope WoW passes ... = (addonName, addonTable), so each table
got two stray junk entries instead of being empty; { ... } is also a
strict Lua 5.0 parse error. Fixed QuestieOptions.tabs and the Arrow,
General, Keybinds, and Tracker tab tables. Cherry-picked from
phase2-lua50-sweep (the only version-independent fix in that branch).
