Synthetics UI won't load certain monitor history components for HTTP monitors

[lucasfcosta]

Kibana version: 8.5.0-SNAPSHOT (On cloud CFT on the 28th of Sept. 2022)

Elasticsearch version: 8.5.0-SNAPSHOT (On cloud CFT on the 28th of Sept. 2022)

Browser version: Version 105.0.5195.125 (Official Build) (x86_64)

Browser OS version: MacOS 12.6

Original install method (e.g. download page, yum, from source, etc.): Cloud CFT snapshot.

Describe the bug: Some of the components in the monitor details page won't load for the new Synthetics UI. That only happens for HTTP monitors.

Steps to reproduce:

1. Create a new 8.5.0-SNAPSHOT instance. You can use the cloud for that.
2. On your new Kibana instance, enable the new synthetics UI in the advanced settings.
3. Go to the Synthetics UI and create an HTTP monitor (you'll probably have to go through the "getting started" first)
4. Wait for the monitor to run and access its details page.

You'll see some of the components never load data (the ones related to run history), although the monitor has finished running according to the top right info block.

Expected behavior: The history of runs should be filled.

@lucasfcosta do you remember if the Last test run and Test Runs panels finished loading and showed No data state, or they kept loading indefinitely?

This will help to understand the bug. I suspect all the panels are showing correct state except the top right panel which is showing stale data (in the screenshot). Because the top header hints pings haven't arrived yet.

Found an issue with the loading states of Test Run panels and fix is underway.
