Title: [backport 3.0.x-juno] Only consider opened projects when computing a project's direct dependencies

When computing a project's direct dependencies, filter out non opened
projects (if a project is open it implies it exists, which is why there is no
need to check for `project.exists`).

Fix #1001714
