Botond Dénes fc5b096f73 imr: value_writer::write_to_destination(): don't dereference chunk iterator eagerly ...

Currently the loop which writes the data from the fragmented origin to
the destination, moves to the next chunk eagerly after writing the value
of the current chunk, if the current chunk is exhausted.
This presents a problem when we are writing the last piece of data from
the last chunk, as the chunk will be exhausted and we eagerly attempt to
move to the next chunk, which doesn't exist and dereferencing it will
fail. The solution is to not be eager about moving to the next chunk and
only attempt it if we actually have more data to write and hence expect
more chunks.
