sluicebox 04bd190e58 SCI: Fix fallback detection for unknown fan games
Fan games are now playable even without detection entries.

Fallback detection takes the name of the game object and maps it to
the ScummVM game id. Prior to this change, if we didn't know the game
object name, we propagated this unknown internal string to the ScummVM
game id for the entry, where it was guaranteed to fail.

Now unknown game object names are mapped to the id for fan games.
