Bug with B2C Sample and API scope

[alex-mason-by]

The below code pointer is hard-coded to the Graph API instead of a custom API. I have two issues with this. First, is that the Graph API will not work with B2C to my knowledge and that is why the B2C Sample makes use of demo.read of Hello API, etc. which also means I have doubts that this sample really works at all with B2C and the silent flow. Second, I would really like to see an example where a scope of a different resource is retrieved by the silent flow that wasn't originally asked for in the login request. I have concerns that this doesn't work or I am misunderstanding how to ask for scopes of different resources incrementally.
