Remove useless parameter

Private function convertToOverloadResults() has two call sites, both:

* inside member functions of the NewResolutionOldInference class
* passing NewResolutionOldInference.languageVersionSettings

Therefore, it is safe to remove this parameter from the signature of
convertToOverloadResults(). The occurence of languageVerstionSetting
in it's return statement will refer (implicitly) to the definition from
its class.
