fix: container creation with --incremental used.

If there is no name provided for a container by the metadata it is
always appropriate to use the metadata version name.  create_mddev
will still add a uniquifying digit to the end so there is little risk
of confusion.
This makes the --incremental code behave the same as the --assemble code.
