Fix trust tests for Posix Support
    
    Test ecxpects auto-detection of trust type, Windows Server 2016 doesn't have
    support for MFU/NIS (SFU - Services for Unix), so auto detection doesn't work
    Fix is to pass extra arguments to the trust-add command,
    such as --range-type="ipa-ad-trust-posix" to enforce a particular range type
