Update strategy to use the Portable Contacts format

[DJphilomath]

For the strategy to be compatible with other libraries using passport, the profile has to comply with the Portable Contact format.
It is referenced in http://passportjs.org/docs/profile

You can read a draft of the spec in
http://hdknr.github.io/docs/identity/poco.html

I changed the profile parser to change from the Microsoft format to the PoCo format. In the strategy, the profile parser is called (it was not called).

I stumbled with this bug while trying to use this passport integration with the loopback-passport-component. With this change the profile can be consumed without any problem.

Excellent, I should have done this before publishing but forgot to come back to it, so this is much appreciated. I will publish as 2.0.0 shortly since this is a breaking change for anyone using the current profile response.
