userportal,webadmin: Multi view table columns inconsistent

- since a463914769e87b5fb55999bcd25d56167b8e3d16 columns
  available in all view would not get removed and would
  always end up at the front of the grid even if other
  columns that can disappear were in front of them. This
  patch fixes that problem.
