Not able to pass limit

Here's my query, selecting that first 10 elements from user's collection.

```users = Repo.all(from(u in UserModel, limit: 4, select: u))```

When I run this I get this errror

```
** (exit) an exception was raised:
    ** (FunctionClauseError) no function clause matching in Mongo.Ecto.NormalizedQuery.offset_limit/5
```
