i18n utils: check not only that the number of printf markers are the same in msgid and msgstr, but also that they are of the same type and order. Sorry, should have done that from the beginning... :/

This should prevent any bug like [#37095] Timeline crash when chose any keying set then press keyframe-insert, to appear again.
