fix(core): Fix test runner in queue mode (no-changelog)

[burivuhster]

Summary

This PR makes test runner work in queue mode. evaluation executions logic is almost identical to manual executions, as it also needs features like pinned data or selecting specific trigger and nodes to start executions from.
Since manual executions were offloaded to workers in queue mode, evaluation executions stopped working properly because execution data was not saved to DB before putting executions into the queue.
