FileCreatorHelper creates a FileBlobImpl on the main-thread and, because of this, we end up executing I/O operations on that thread, slowing down other components. With this patch, FileCreatorHelper logic is moved to PBackground. That the 'type' getter is still called on the main-thread because FileBlobImpl uses nsIMIMEService which is a non thread-safe component.
