[BUG] Git from-oci fails if more than one to-oci has occurred

[nathan-joslin]

ace-dt git from-oci fails if more than 1 ace-dt git to-oci action has occurred for the same reference.

Reproduce:

• ace-dt git to-oci inital full bundle push
• ace-dt git to-oci shallow bundle push
• mkdir test && cd test && git init
• ace-dt git from-oci <oci-ref> file://<absolute-path-to-test-dir> fails

Error:

Error: rebuilding (OCI) "127.0.0.1:5000/test-ace-dt:sync" to (Git) "file:///tmp/test-ace-dt/": updating intermediate repo from OCI: fetching from bundles: exit status 1
git ["git" "fetch" "changes3" "--tags" "--multiple"] produced an error: error: Repository lacks these prerequisite commits:

This should be addressed upstream by refactoring with gnoci once it's updated with the performance requirements we need.
