This appears to be working correctly in master (there's a passing test too). What's the issue?

@fluffynuts

• Case 1:
  linkedList.addAt(0, 1);
  linkedList.addAt(0 ,2);
  output : { data: 1, next: Node { data: 2, next: null } }
• Case 2:
  linkedList.addAt(0, 1);
  linkedList.addAt(0 ,2);
  linkedList.addAt(2 ,3);
  output: { data: 1, next: Node { data: 3, next: null } }

There can be more cases where it can fail
