at specified position. At least in case of ScUndoPaste, during
undo operation, the content from changed area in main-document
is removed before actual undo-paste, so when cloned formula-cell
from undo-doc is inserted to main-doc, there is no "old" cell
to detach, so "rNewSharedRows" is not populated which is needed
for proper re-establishment of listeners if there are formula/
formula-groups adjacent to insertion position.

Next: fix the vector version of this case and write unit tests.
