Describe the Bug

processIndexingAndIPNICleanup panics when creating an IPNI removal advertisement because the Entries field is nil.

panic: interface conversion: datamodel.Link is nil, not cidlink.Link

github.com/ipni/go-libipni/ingest/schema.signaturePayload
    go-libipni@v0.7.1/ingest/schema/envelope.go:89
github.com/filecoin-project/curio/tasks/pdp.processIndexingAndIPNICleanup.func1
    tasks/pdp/watch_piece_delete.go:333

The schema.Advertisement is created without Entries at watch_piece_delete.go:294-299, but Sign() requires it.

Workaround

Comment out processIndexingAndIPNICleanup call at watch_piece_delete.go:47-50.
