IsVerbatim not working with multiple queries

[EricKeij]

Following up on #1872.

IsVerbatim works fine on a single TermQuery but i can't seem to get it to work when combining mutiple queries.

var container = new QueryContainer(new TermQuery
{
 Field = "surname",
 Value = ""
});

container &= new TermQuery
{
 Field = "age",
 Value = "10"
}

((IQueryContainer)container).IsVerbatim = true;
ElasticClient.Search<MyType>(new SearchRequest { Query = container });

This results in

POST /<index>/<type>/_search
{
   "query": {
      "term": {
         "age": {
            "value": "10"
          }
       }
    }
}

While I expect

POST /<index>/<type>/_search
{
   "query": {
      "bool": {
         "must": [
         {
            "term": {
               "surname": {
                "value": ""
             }
           }
         },
         {
            "term": {
                "age": {
                "value": "10"
                 }
             }
          }
       ]
    }
  }
}

Thanks @EricKeij

This also looks to be an issue using the fluent API as well. I'm working on a fix for #1876 in this branch and will make sure this gets covered as well.

Pushing this to 2.2.
