@current_user.name is nil for Google Authentication about ueberauth_example

[bezborodow]

I managed to fix this by adding default_scope: "email profile" in config/config.exs as follows:

# Überauth
config :ueberauth, Ueberauth,
  providers: [
    google: {Ueberauth.Strategy.Google, [
      default_scope: "email profile",
      ...............
    ]}  
  ]

@bezborodow would you be willing to open a PR to update this project's configuration and perhaps add a note to the README here and ueberauth_google if it's not already mentioned?
