tdf#120387 get lock to use ImpEditView::CutCopy

ImpEditView::CutCopy releases the SolarMutex to handle clipboard
access. So lock the SolarMutex when accessing this function
through OutlinerView::Copy().

Now all paths effectively need the SolarMutex, so remove all the
intermediate locking. I guess the explicit release for the
xTransferable.is() test isn't needed.
