Title: Keep the default behaviour to apply transformRequest

Angular apply transformRequest using 3 parameters

- data: the object which contains all parameters
- headerGetter: a function which return the header value of a key or if there is no keys the header object
- transformRequest: the array of functions to pre-process your data

This code allow to restaure this behaviour and then add those processed parameters in the formData
