[boskid][2.0.60] Loaders stop taking asteroid chunks from collector

[kryojenik]

A loader attached to an asteroid collector will (if full) initially output to both lanes of a belt. It will stop outputting asteroid chunks if one lane gets backed up.

Conditions:
- One lane is backed up / blocked. See attached screen shot.
- Initial flow on free lane is interrupted (empty collector)
- New chunks are collected by the collector

This behavior does not happen with chests.

Attached is a save game demonstrating the behavior.

Thanks for the report. Issue is now fixed for 2.0.61.

Reason why it only happens with asteroid collectors is because they do not provide wakeup lists and there was a logic flaw inside of a loader that would not force keep it active when it failed to get a wakeup list from the entity it takes items from.
