SearchRaw & .FacetItems Throw Exception w/ Latest Commit

[nariman-haghighi]

The following line is now generating an exception because this.Infer is null for .SearchRaw calls:

        public IEnumerable<F> FacetItems<F>(Expression<Func<T, object>> expression) where F : FacetItem
        {
            var fieldName = this.Infer.PropertyPath(expression);
            return this.FacetItems<F>(fieldName);
        }

Great spot @nariman-haghighi 👍 This happened because when you used NEST typed responses with low level Elasticsearch.Net calls .ConnectionStatus would not be set causing .Infer to misbehave on NEST's BaseResponse.

The "magic" that sets this property now actually lives in Elasticsearch.Net.
