Provide source_file_id with print file

Had to implement this a bit differently as stated in the ticket. This field is returned when uploading the project file.

Logic needed a bit of a change as the new behavior dictates a sequence (we can only upload the print file after the project file is uploaded, and we know the correct `file_id`/`source_file_id`) where before these two api calls were done in parallel.
