Subject: [PATCH] Type streamy (#275)

I think the recent change to scan that added the call to `type` is
breaking me because I'm using streams. I'm getting the following stack
trace:
```
    ArgumentError:
       Not sure how #<MockRedis::Stream:0x00007fcceb5db3e8 @members=#<Set: {[#<MockRedis::Stream::Id:0x00007fcceb5db2d0 @exclusive=false, @sequence=0, @timestamp=1691767286667>, {"kind"=>"created", "type"=>"group", "data"=>"{\"name\":\"DEFAULT\",\"scope\":\"TEST\",\"updated_at\":1691767286666973366}"}], [#<MockRedis::Stream::Id:0x00007fcceb5e3278 @exclusive=false, @sequence=1, @timestamp=1691767286667>, {"kind"=>"deployed", "type"=>"group", "data"=>"{\"name\":\"DEFAULT\",\"scope\":\"TEST\",\"updated_at\":1691767286666973366}"}]}>, @last_id=#<MockRedis::Stream::Id:0x00007fcceb5e3278 @exclusive=false, @sequence=1, @timestamp=1691767286667>> got in here

```

I think this addition to add `streamy` to `type` will fix it. Not sure
where in the tests this should go ...
