Description

The following redis TCL test fails when running against Geode for Redis:

        # Geode fails with: Expected '1' to be equal to '0'
        test "ZUNIONSTORE against non-existing key doesn't set destination - $encoding" {
            r del "{slot}zseta"
            assert_equal 0 [r zunionstore "{slot}dst_key" 1 "{slot}zseta"]
            assert_equal 0 [r exists "{slot}dst_key"]
        }

Enable this test as part of this fix.
