Michał Chojnowski a24f83852e atomic_cell: fix operator<< for atomic_cell_or_collection ...

operator<< used the wrong criterium for deciding whether the data is
stored as atomic_cell or collection_mutation, resulting in
catastrophical failure if it was used with frozen collections or UDTs.
Since frozen collections and UDTs are stored as atomic_cell, not
collection_mutation, the correct criterium is not is_collection(),
but is_multi_cell().

Closes #8134
