Google: Handle missing $primary property for placesLived

Google returned the following for my profile:

    [placesLived] => Array
        (
            [0] => stdClass Object
                (
                    [value] => Mödling
                )

        )

So there is no primary property of `$c`.

The code now checks if there is a `$primary` property and otherwise directly uses the `$value` if it exists.
