* Docs say: call sqlite3_close even when sqlite3_open returns error * Be careful of possible failures of AutoSave... ... In ProjectHistory operations, do the AutoSave first and throw if there is a failure. Only then change UndoManager's state, confident that it remains consistent with what was AutoSaved. * Throw exceptions if lazy opening of project's database fails... ... because the calls to DB() as in Sqlite3SampleBlock may be in deeply nested places that can't propagate the error codes; and besides, those functions had been assuming non-null returns from DB(), which might have crashed before, but now the assumption is correct when the throw didn't happen. Note that this exception may also happen during attempted Autosave. Uses of Autosave were reviewed and some changes made in the previous commit.
