Schema invalid: Invalid value types

[mtarld]

In Magento1 vsBridge, json response is created using json_encode with JSON_NUMERIC_CHECK flag.

Therefore, every string that look like integer is casted as integer.
That's a good thing, but that creates some bugs:

• Fields such as telephone, postcode, ... must be strings according to vsf schema. That's why vsf doesn't validate data.
• Numbers like '06467' will always be returned as '6467'
• cart id is returned as integer but should be string (then order cannot be placed)
