[Bug] PayPal button does not appear in "pay with paypal" form

[jorisduenas]

Hello,

PayPal button does not appear in "pay with paypal" form:

The paypal sdk wont load and i have this error in my console:

/**
throw new Error("SDK Validation error: 'Invalid query value for locale: fr'" );

/* Original Error:

Invalid query value for locale: fr (debug id: ***)

*/

Sylius locale codes are used to request the paypal sdk. So does not work when the local codes of sylius are different from paypal codes.

The problem is similar to this one: 188

I think the LocaleProcessor could solve the problem.
