ERP5Type: Disallow restricted python from calling immediate reindexation methods

Calling these can break catalog by not caring about concurrent indexation
activities. Even non-restricted code should not call these, but:
- they cannot be reliably renamed, as there exist activity dependencies
  looking for these exact names (which is a bad practice on its own)
- there is no simple access control mechanism for non-restricted code
So rely on developer discipline instead.
