sed added for check only two user

https://gitlab.e.foundation/e/infra/backlog/-/work_items/5428

Test Case 1: Without sed applied (performance issue observed)

• Ensure no sed modification is applied to the code

  • Keep the function as:

    private function isOnlyUser(): bool {
    return $this->userManager->countUsers() < 2;
    }

  • Deploy or run the application in this state

  • Trigger the functionality that calls isOnlyUser()

  • Monitor logs

  • Observe execution time (expected: ~11 to 30 seconds)

  • Verify logs show slowness or delay

    

Test Case 2: With sed applied (performance improved)

• Apply the sed command to modify the code
  • Deploy the sed
  • Trigger the same functionality that calls isOnlyUser()
  • Monitor logs time
  • Observe execution time (expected: fast response)
  • Verify no slowness logs are generated
