Torus requires a title attribute on a Figure element. Legacy figures did not need to include a title, giving rise to a rendering failure on migrated untitled figures with message "unsupported content element: figure". This change has migration tool insert an empty title in this case. Also adds the step of "elevating" content in a figure's child title element in the original XML to a title attribute in the json figure object, which it appears was not being done.
