PR Checklist

PR Structure

  • This PR has reasonably narrow scope (if not, break it down into smaller PRs).
  • This PR avoids mixing refactoring changes with feature changes (split into two PRs
    otherwise).
  • This PR's title starts with name of package that is most changed in the PR, ex.
    services/friendbot, or all or doc if the changes are broad or impact many
    packages.

Thoroughness

  • This PR adds tests for the most critical parts of the new functionality or fixes.
  • I've updated any docs (developer docs, .md
    files, etc... affected by this change). Take a look in the docs folder for a given service,
    like this one.

Release planning

  • I've updated the relevant CHANGELOG (here for Horizon) if
    needed with deprecations, added features, breaking changes, and DB schema changes.
  • I've decided if this PR requires a new major/minor version according to
    semver, or if it's mainly a patch change. The PR is targeted at the next
    release branch if it's not a patch change.

What

Fixes SignersProcessor to insert sponsorship information during state ingestion from history archives.

Why

SignersProcessor operates in two modes: useLedgerEntryCache set to true or false. When ingesting history archives we use useLedgerEntryCache=false to save memory - ledger entry cache is not needed because there are only inserts. This code path was not updated to include information about the sponsor of a signer.

Known limitations

If we decide to release it in 1.9.1 we should update CHANGELOG.

…on test (#3127)

All integration tests start from empty state so we don't test building
state from history archives. Extended state verification integration
test to trigger state rebuild (`horizon expingest
trigger-state-rebuild`) and verify rebuild state again. Such test would
catch the bugs like #3100 and #3096.
