HGETALL returns array instead of hash

[raphaottoni]

Acessing the key from redis-rb gem using hgetall return a hash:

when accessing the same key with a lua script using redis-rb-scripting it returns a array:

hmget.lua

Same problem occur with wolverine gem:
Shopify/wolverine#13

This is because the redis-rb gem does special processing on the return value of hgetall, you can see how the return value is processed through the _hashify method before returning https://github.com/redis/redis-rb/blob/master/lib/redis.rb#L2013

You can see the same behavior without this gem, just calling eval on the redis connection directly. You'll just need to do the processing yourself when doing it via a lua script.
