[iOS/tvOS] UserSecrets.Test.ConfigurationExtensionTest.AddUserSecrets_With_SecretsId_Passed_Explicitly fails on devices

[steveisok]

The test fails with:

System.UnauthorizedAccessException : Access to the path '/private/var/mobile/Containers/Data/Application/23FFD2C4-8226-4FCD-A938-6043BA920C7E/.microsoft/usersecrets/29dfe5f3-363f-4c6a-bf88-358fe2605ae7' is denied.
---- System.IO.IOException : Operation not permitted
Stack trace
   at System.IO.FileSystem.CreateDirectory(String fullPath)
   at System.IO.Directory.CreateDirectory(String path)
   at Microsoft.Extensions.Configuration.UserSecrets.Test.ConfigurationExtensionTest.SetSecret(String id, String key, String value)

   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

The problem on iOS/tvOS is that the HOME directory is not writeable. The value returned from

runtime/src/libraries/Microsoft.Extensions.Configuration.UserSecrets/src/PathHelper.cs

Line 48 in 1c949ac

?? Environment.GetEnvironmentVariable("HOME") // On Mac/Linux it goes to ~/.microsoft/usersecrets/

will trigger the failure.
