[Infra UI] Hosts view test: fix apm services link (#162147)

Closes #162051
Closes #159368
## Summary

This PR aims to make the APM services link test more stable. For some
reason, some of the query parameters are not present in the URL the
moment we navigate but we can see in the screenshot that the correct
dates are applied (it could be that the moment we load APM the URL is
not updated - when checking locally those parameters exist in the URL)
