* Update plugins/delete-project from branch 'master'
  to ae4ee2acf4a72c508d079ccd9666a64e8bcf6dae
  - Merge "Send project-deleted event after project deletion"
  - Send project-deleted event after project deletion
    
    Gerrit EventDispatcher has two types of listeners: user restricted or
    unrestricted. For the restricted listeners before sending the event
    Gerrit checks if user has permission to access the project. This means
    that `project-deleted` event will not be delivered to the restricted
    listeners because when we send the event project is already removed
    so we cannot check permissions anymore.
