fix: Undo takes back theme changes, section colours and notebook properties

Saving in the Themes dialog is a step on the window's undo timeline: Undo puts the
themes and the scope's theme back and restyles the page, while what it wrote still
holds. A section's colour and Notebook Properties' name and colour go back too.
