Weird integration test for `@PostMapping` with Spring Security

[ancavar]

To Reproduce

1. Add Spring Security.
2. Generate integration test for @PostMapping, e.g.

   @PostMapping("/demo")
   public String demo() {
       return "demo";
   }

   Expected behavior

Probably shouldn't have this test.

Actual behavior

    ///region FUZZER: SUCCESSFUL EXECUTIONS for method demo()

    /**
     * @utbot.classUnderTest {@link NameController}
     * @utbot.methodUnderTest {@link NameController#demo()}
     */
    @Test
    @DisplayName("demo: ")
    public void testDemo() {
        String actual = nameController.demo();

        String expected = "demo";

        assertEquals(expected, actual);
    }
