Remove call to repo search endpoint during the "rooms, people, messages" search
During the "rooms, people, messages" search we are performing search for user's repositories. This action doesn't make sense from UX perspective since the UI clearly says that we search for "Rooms, People and Messages".
This unexpected repo search call was partly a cause of the API memory incident gitlab-com/gl-infra/infrastructure#9673 (comment 317544981)
This issue is to remove the repo search endpoint call from webapp search.
