Test-Path returns "True" when path doesn't exist

[MouseFortune]

Steps to reproduce

In a non elevated PS window test a path which you don't have access to (such as below).

Test-Path registry::HKEY_USERS\S-1-5-19\SOFTWARE\Microsoft\Office\16.0\Common\MailSettings

Performing the action in an elevated PS window will give you the expected value

## Expected behavior
Test-Path registry::HKEY_USERS\S-1-5-19\SOFTWARE\Microsoft\Office\16.0\Common\MailSettings
Returns: False
Key does not exist

Actual behavior

Test-Path registry::HKEY_USERS\S-1-5-19\SOFTWARE\Microsoft\Office\16.0\Common\MailSettings
Returns: True
