Converting a large list to a connection.

Hey,

So I used to do this to create my connection:

```
Connection()
.Name("liveStreams")
.Resolve(c =>
{
var liveStreams = liveStreamService.GetAudios();
var splitLiveStreams = ConnectionUtils.ToConection(liveStreams);

return splitLiveStreams;
});
```

However the code internally calls `.ToList()` which means that for every page it is returning all of my 25k records from the database and it would be incredibly slow obviously.

So instead of doing this I now do:

```
Connection()
.Name("liveStreams")
.Resolve(c =>
{
var offset = ConnectionUtils.OffsetOrDefault(c.After, 0);
var liveStreams = liveStreamService.GetAudios();
var newLiveStreams = liveStreams.Take(c.First.Value + (offset + 1));
var count = liveStreamService.GetCount();
var splitLiveStreams = ConnectionUtils.ToConnection(newLiveStreams, c, 0, count);

return splitLiveStreams;
});
```

`
public IQueryable GetAudios() {
return _repository.GetAll();
}
`

So this doesn't load the entire 25k records anymore, only the data I need.

Is this the correct way to do this or am I doing something wrong? It was very hard to figure this out and I feel it may be the wrong way.

I'm using Entity Framework core.

Thanks.
