generate-helper-types causes System.IO.IOException

[ujos]

In case if I add --config generate-helper-types key to the command line, I get an exception:

Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.IO.IOException: Cannot create '...\PInvoke' because a file or directory with the same name already exists.
