sw: fix missing OLE preview on updating links

Regression from commit 74844277cc2194c9e43f5bd7a6f78a9603da32f3 (disable
generation of ole previews in ODF format until after load, 2016-09-13),
if the document has charts without previews, it's loaded, fields are
updated and saved, we no longer generate those previews.

Given that Tools -> Update -> Update all is always an explicit user
action, restore the permission to update OLE previews / links before
performing the actual update.

With this, comphelper::EmbeddedObjectContainer::StoreAsChildren() will
generate those missing previews inside the getUserAllowsLinkUpdate()
conditional block.
