Remove broken cookie on checkout script

[lucasecdb]

What is the purpose of this pull request?

This PR removes the cookie with the name [Object object], which affected the cart cookie on Checkout API.

What problem is this solving?

The cookie has invalid characters that the .NET Framework can't parse, and because of this the API can't read the cart cookie if this other cookie is present in the request headers.

How should this be manually tested?
