Calling beginEditBlock() triggers a textChanged() signal and
did "confuse" Qt Quick Designer.

We could just suppress the signal to work around the issue, but I think
it is cleaner to not alter the text document in autosave at all.

Changing the current text document in autosave might have other
unforeseeable implications.

What happened in the Qt Quick Designer was that textChanged() triggered
a reload of the document.
While the reload of the document usually just triggered a
short/unnoticed dealay, it can also trigger a message box with warnings.

Since we (correctly) assume the .QML file was altered outside
of Qt Quick Designer we do sanity checks and warn about code that
might not be supported.

Having those warnings whenever a file is autosaved is annoying.

the regular case is the more complex one, so put that into the base class.
