GEODE-8387: fix SET*STORE commands handling of empty results (#5405)
> SUNIONSTORE, SINTERSTORE, and SDIFFSTORE should delete the target key if the
> computed set is empty

>
> The current impl of SUNIONSTORE, SINTERSTORE, and SDIFFSTORE set the
> destination to an empty set if the computed set is empty. But they should
> instead in that case delete the destination. This is true if the read keys do
> not exist.
> If the read keys exist but are not sets then the commands should fail with a
> WRONGTYPE error.
