text: Title: `Lists Should Be Equal` does not work as expected with `ignore_case` and `ignore_order` arguments
  Body: Looks like 'Lists Should Be Equal' does not work in one of the scenarios as mentioned below
  
  ```
  ${list1}    Create List    AbC    AEF
  ${list2}    Create List    AEF    ABC
  Lists Should Be Equal    ${list1}    ${list2}    ignore_case=${True}    ignore_order=${True}
  ```
  We are expecting this to be passed since the lists are same as we are ignoring the order and the case. However, It is failing. 
  
  Can someone explain reason behind it please? Does it have something to do with ASCII codes
  
  I would be glad to provide additional details if required. Thanks
