go/registry: Add support for querying suspended runtimes

[ptrus]

Fixes: #3093

TODO:

• fix the runtime_dynamic test
  • actually cannot reporduce this in the runtime dynamic test (or locally anymore), so it might have worked fine even before (even if the node fast-syncs it still get's all the events during fast syncing so it does get notified of the suspended runtimes). Nevertheless this change is still useful.
