Description

The ProjectsController#show action always queries for subprojects using @project.children.visible.to_a, even when the current project is a leaf and has no subprojects.

  Project Load (0.2ms)  SELECT "projects".* FROM "projects" WHERE "projects"."parent_id" = ? AND (projects.status <> 9 AND projects.status <> 10) ORDER BY "projects"."lft" ASC  [["parent_id", 5]]
  ↳ app/controllers/projects_controller.rb:179:in 'block (2 levels) in ProjectsController#show'

This patch adds a check using @project.leaf? to skip the unnecessary query when the project has no children.
