Title: Tolerate multiple calls to entity.manage()

- Instead of exception, just warn and ignore.
- Required because on rebind if a policy creates an entity while still rebinding other entities (while calling onManagementStarting on each), then when iterating over all to call onManagementStarted it will fail if one of those referenced entities is already fully managed.
