Address increased number of fallback tracking
We need to investigate the [huge spike](https://gitlab.com/gitlab-data/analytics/-/work_items/27100#note_3307300493) in events caused by FallbackOrganizationTracker
This spike coincidences with the merge of https://gitlab.com/gitlab-org/gitlab/-/merge_requests/226038+
Each time `Current.organization` is called, we emit the event.
The purpose of the event is to track in which cases we can't resolve to an organization.
Investigate:
- Do we still need it
- Do we _always_ call the 'trigger' method or only if the fallback organization is used?
- Can we limit the number of times this event is triggered?
- Alternative implementation possible?
