QQuickTableView: override fixup() to preserve contentX/Y at start-up

Flickable::fixup() will be called from Flickable::componentComplete().
fixup() is a virtual function that subclasses can override to e.g
ensure that cells snap to grid etc (which is not yet supported by
TableView). The default implementation will check if the assigned
contentX/Y is within the current content item size, and adjust it
back to 0,0 if not. The problem is that during componentComplete(), the
table has not yet been built. And we don't want Flickable to reset
any assignments to contentX/Y until that has happened. So override the
function and block it from doing any adjustments before the table has
been built.
