cool#9352 unassign cursor on SdrObjEditView to avoid crash

On stress test with shapes and typing a segfault ocurred due to
using a freed vcl::Cursor.

On SdrObjEditView::SdrEndTextEdit, delete pOLV can delete the cursor
remembered in pTECursorBuffer. But if it is set to the window before
the deletion, it will be safely removed from the window.

And on SdrObjEditView::ModelHasChanged a re-anchoring sets a cursor
on the window that sholdn't be there and other SdrObjEditView can
see, remeber, and use it even after this one died and freed the
cursor.
