Rename projects set for delayed deletion

What does this MR do and why?

• When marking a project for deletion, appends deleted-{project_id} to the end of the project path and title.
  • This frees up the original project name to be used by another project immediately.
• When restoring a project, resets the project name to its original name unless the project name has been taken in the mean time.
  • In this instance, the project is given a random alphanumeric suffix.
