fix #2274
When Moby adapters are used without containerd backend, the descriptors are lacking the original compressed layer digest and there is a workaround to link in the uncompressed digest. If a build exporting the cache also imported it from the registry then the original imported records with compressed digest needs to be exported as well. If there were another exported records that referred to the same layers via the uncompressed digest through parent layers then such records could be overwritten and the original provider from cache import could get lost.
