- fixed some more places with an explicit AUTO_WRITE.

BUG: revert handling of the readOption. It should not be NO_READ.

  In cases where the user a IOobject without specifying read/write, it
  defaults to NO_READ anyhow. However, the move constructor can also
  be called with empty lists and a read option. This has the same
  signature, but obviously will not work with NO_READ.
