Honour scale definition per print 'Folha' definition

[fernandinand]

Example:

[{
    "page_id": 1,
     "params":{
              "default_scale":2000
              },
...
},
{
    "page_id": 2,
     "params":{
              "default_scale":25000
              },
...
}]

Currently, if you have n pages print configuration with different scale definition per print page, the first page scale definition is propagated for all other pages on print config.

Expected:

Scale definition should be honored per page configuration in order to have different scale definition along a multipage print configuration.
