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

This adds tests for predicates on claimable balances.

It first checks the happy paths, ensuring that all predicate types can be created and that valid predicates result in actually claimable balances.

It also checks that predicates actually matter: both an unconditionally-false predicate and an expiring timer cause the claimabe balance to be irretrievable.

Why

Further testing of CAP-23 (see #2939) and specifically of #3000.

(sorry about the weird commit history... should go away w/ squash & merge)

Why would we ever want a predicate that always fails?
