In CE, every `Issue` entity is also a `ProjectEntity`, which calls
`entity&.project.try(:id)` to show the project ID. In an API
request with 100 issues, this would hit the Rails statement cache 100 times
for the same project and cause unnecessary overhead as related models would
also be loaded.

In EE, we call `Issue#supports_weight?` for each issue, which then calls
`project&.feature_available?(:issue_weights)`. If the project is not
preloaded, this incurs additional overhead, as each individual Project
object has to be queried. This can lead to a significant performance hit.
In loading the CE project with 100 issues, this contributed to at least 22%
of the load time.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/47031 for why testing this
is a bit tricky.

Fix   after sign-in with Google button

the current syntax doesn't work properly in Rails 5, the resulting query
looks like:
HAVING "events"."project_id" IN (0)

instead of:
HAVING "events"."project_id" IN (SELECT "projects"."id" FROM...

Also we should not use ActiveRecord internal methods. In this case we
can filter projects in WHERE clause instead of doing this in HAVING
clause. Usage of WHERE should be also more efficient because grouping
is then done on much smaller subset of records.
