Fix LSM30:Fetch guards - also check LSM30.Fetch exists before calling

Previous guard only checked LSM30 ~= nil; if Fetch method is absent on
the stub object the call still crashes. Now uses full 3-part check:
  (LSM30 and LSM30.Fetch and LSM30:Fetch(...)) or fallback
Matches the pattern already used in QuestieArrow.lua.
