Remove locale switching from DOMPDF::_process_html

DOMPDF::_process_html performs locale switching to avoid formatting issues, but it is called by DOMPDF:process which also performs locale switching. This nested locale switch breaks recording of the original locale resulting in the incorrect locale setting after dompdf runs (on systems where the local is incompatible with dompdf).
