Mixed casing prevents multiple readPreferenceTags in uri string

      The URI

      mongodb://mongos1.example.com,mongos2.example.com/?readPreferenceTags=foo:bar&readPreferencetags=dc:ny

      If there are two entries in the URI for readPreferenceTags, and one is case-insensitive it is not appended to the parsed readPreferenceTags

      This returns:

       

      { readPreferenceTags":[{"dc":"ny"}] }

       

      Should return:

      { readPreferenceTags":[{"foo": "bar"}, {"dc":"ny"}] }

       
      I believe this occurs because the query parser will gather same-value key as an array. But because they don't have the same key the latter value is overwriting the previous.
