Make after-change-function save match data.

elpy-folding--mark-foldable-lines disrupts editing activities, like
query replace, because it fails to save match data.

Here's relevant instructions from the Elisp Manual (in Emacs 26.3):

32.30 Change Hooks
 ...
"The functions you use in these hooks should save and restore the match data if they do anything that uses regular expressions; otherwise, they will interfere in bizarre ways with the editing operations that call them."
