Find - Allow stemming when using Synonyms in a Typed search without specifying .InFields()

Currently, stemming doesn't work in a Typed search when .UsingSynonyms() is used but .InFields() is not specified.

For example, this breaks stemming:

var result = SearchClient.Instance.Search<T>(Language.English)
.For(query)
.UsingSynonyms()
.GetResult();

Thanks
