Problem: signature is sometimes missing from event when using Dexie cache

[gsovereignty]

Signatures are very often missing on events whenever Dexie cache is used.

I thought it may have been something retarded in my implementation at https://github.com/nostrocket/hypergolic/ but this is now reproduced with https://github.com/bob2402/reproduce-lost-signature

The events do have valid signatures, but NDK is stripping them out somewhere.
