Fix Faker::Vehicle Array Access

[rui-ribeiro]

Just a little fix accessing the array.

I don´t know if this is the best way to fixed, feel free to comment.

Fixs #627

See PR #644

@rui-ribeiro Your PR is right. But test cases related to Vehicle are faild. The reason behind it is, when you access this

manufacture = fetch_all('vehicle.manufacture').sample

In your app, it returns hash whose keys are symbols. And when you run test cases it returns hash whose keys are strings. Strange behavior.

[rui-ribeiro]

Yes, exactly that. I don´t know why it behaves like that, must me some require or extension.

That´s why i referenced PR #644 because of the conversion of the hash for indifferent hash.

Another solution for this problem is, You can use or( || ) in your code.
For Example: In vin method you can write like

vehicle_identification_number = (manufacture['wmi'] || manufacture[:wmi]).split('').concat( Array.new(14) { c.sample } )

It will solve both problems. thanks
