Change a symbol's information without building its folio (stage D5)

Browse Source 
A script changing the information of a symbol on a folio not built, when
nothing else shows that information (no symbol built holds it, no
partner is linked to it, no label formula), changes it through the
project database: the store and the symbol's element info row, undoable
by uuid (ChangeStoredElementInformationCommand). Reading it back reads
the store. Building the symbol later takes the change
(projectDataBase::takeUnbuiltEdit(), in Element::fromXml()), the label
and texts following as for any change. Saving a .qetz writes the
changed information in the database in place of the rows the folio was
read with, its file copied, the folio still not built; a symbol whose
file holds no information block, or a .qet, builds the folio to save.

136-folio .qetz, "comment" set on the 3 513 symbols the database can
change: 0.9 s, no folio built, saved in 6.1 s, none built (27 s and 116
folios when saving built them). The same edits on the 4 039 symbols with
no partner and no formula, lazily and with every folio built: the two
saved projects are the same file. tst_lazyfolios: a script changes a
symbol not built, building none; saved as when built (fails when
building ignores the change, and when the .qetz writer does); undone;
the folio built afterwards shows it. ctest 96/96 eager and lazy; 342
corpus projects save the same in all four arms and export the same.
