Great work!
Have another one test case to add.

1. Assign second task created in the project to admin user
2. Login with second user
3. Go to tasks page, there is only should be first task from project

Test case added. Also I move cypress command for projects functionality to different command file (commands_projects.js). I think it`s would be better for readability.
