Use of arrays as command arguments

[mapolonio]

In the node_redis official documentation they state that arrays can be used along with individual arguments (see https://github.com/NodeRedis/node_redis#sending-commands). But in redis-mock the behaviour is not the same:

(I have promisified the client)

const client = redis.createClient();

await client.saddAsync('mySet', ['a', 'b', 'c']);

const members = await client.smembersAsync('mySet');

console.log(members);
// In node_redis: ['a', 'b', 'c'] (3 members)
// In redis-mock: '["a", "b", "c"]' (1 member, the array stringified)

Just stumbled upon this issue. Can it be fixed?

[mapolonio]

I ended up doing something like this

const originalMethod = client.saddAsync;

client.saddAsync = function(...args) {
      return originalMethod(..._.flatten(args));
};

@yeahoffline I've just created a PR to fix this issue. Can you have a look at it? Thanks.
