  Checks if a insert operation should be allowed. Invoked when a Past node receives an insert request and it is a replica root for the id; invoked on the object to be inserted.

    `checkInsert` in interface `PastContent`
  Overrides:
    `checkInsert` in class `PastRegrTest.TestPastContent`
  Parameters:
    `id` - the key identifying the object
  Returns:
    null, if the operation is not allowed; else, the new object to be stored on the local node.
  Throws:
    `PastException`
