wicked_pdf changes Content-Type to application/pdf if save_only is true

[fiftin]

I try render html view after I rendered pdf to file. But received error becouse Content-Type changed to application/pdf. I need explicit specify content_type during rendering to fix this issue.

def send_mail
  render pdf: 'product-list', save_only: true, save_to_file: PDF_FILENAME
  render 'product_list/send_mail' #, content_type: 'text/html'
end
