Fix flaky cycle analytics spec

What does this MR do and why?

Fix flaky cycle analytics spec.

Specs running around 23:00 UTC always fail because within the spec one more hour is added to the current time before creating some objects, this causes some objects to be created in the next day and kept out of the filter.

Example of failures:

• https://gitlab.com/gitlab-org/gitlab/-/jobs/8027467872
