userportal,webadmin: auto reselect fix

- When only one row was visible in the main
  grid the application would auto reselect the
  row even after the user had manually deselected
  the row. This patch fixes this so as long as
  the data is not manually refresh (either the
  button or selecting another tab). It won't
  reselect the row.
