With a .qetz and lazy folios (both the default), changing only the
title, author, date or revision of a folio holding a picture, while that
folio was not displayed, then saving, gave a .qetz that refused to open:
'picture "images/<sha>.png" is missing'.
Such a folio is saved from its items as read, with its new header
(Diagram::deferredXmlWithHeader()). Read from a .qetz, its <image> names
its picture's file (qetz-file) instead of holding the picture, and
QetContainer::split() takes out only pictures held inline: the file was
never written, while the folio still named it. The folio now gets its
pictures written in, from the bytes the project keeps
(QETProject::containerPicture()), as a built folio writes them.
On master, a picture on folio 2 of grafcet, iso_sfc_example, 741,
tremie_vibrante or Projet_vierge is lost this way; found on three forum
projects by comparing lazy saves with saves of every folio built. Saving
as .qet was not affected.
New tst_qetzheaderpictures (grafcet.qet: picture on folio 2, saved as
.qetz; its title changed with folios built when needed; reopened with
its picture and title): fails without this change ("picture ... is
missing"). ctest 107/107.
