Update git submodules

* Update plugins/delete-project from branch 'master'
  to 8851ed4bf55476fe9997de03693b2561ef6f6f15
  - Merge "Handle 204 response in delete-project"
  - Handle 204 response in delete-project
    
    This change causes calls that fail without throwing an exception
    to no longer display a message below the "Delete Project" itself, but
    rather shows a new modal window with the details of the error.
    
    If a call fails, throwing an exception, the error will be displayed as
    before.
