This is to mirror the preloads logic on Projects::Dashboard
controller. The dashboard and search view both share the same project
view partial (i.e. `_project.html.haml`) and require similar project
data for presentation.

The N+1 test was failing to pick up this N+1 issue as it uses the same
associations for project test data and these queries are cached. This
change ensures that we skip cached queries and count everything.
