Raise NotFound error when retrieved by not uuid
Raise NotFound error when retrieved by not uuid

On identity-projects page:
  Retrieve project list filtered by id which is not uuid format like '%',
there will throw an error message on top-right page.
And the same for identity-users page.

It is reasonable that return an empty list without error prompt.
