Top Fetch misbehaviour when using afanasy scheduler

[nuclearpolygon]

issue

top fetch does not report work items back

expected behaviour

When the remote TOP network is cooked, the work items on the output node of that network are saved to disk and reported back to PDG. Then these items are re-created in the TOP Fetch node. The items visible on the TOP Fetch node are those re-created items.

actual behaviour

When the remote TOP network is cooked cooking process stops and no work items appears in top fetch

steps to reproduce

1. create topnet1 and place generic generator into it, make afanasy scheduler the default one for the network
2. create topnet2 and place topfetch then point it to topnet1/genericgenerator1, make afanasy scheduler the default one for the network
3. cook topnet2
