Postpone data-parsoid saves until DOMPostProc is done

This is an attempt at making things faster by eliminating repeated
load/save of data-parsoid.

Outputs data-parsoid and the rest in the HTML when specified by a dump or
trace flag, as it did before we were using properties in the DOM.

Added missing options arg to handleUnbalancedTableTags
