withBody() and withBodyFile() are ignored

Describe the bug Version: knotx-junit5:1.5.0 When a mock server is created with the @KnotxWiremock annotation, the mapping methods withBody() and withBodyFile() of ResponseDefinitionBuilder are ignored and the mock tries to load a response from a file instead.

To Reproduce Steps to reproduce the behavior:

Create a mock server, using @KnotxWiremock, eg. @KnotxWiremock(port = 4000) protected WireMockServer mockServer;
Create a mapping, using withBody() or withBodyFile(), eg. stubForServer(mockServer, get("/get-data.json") .willReturn(aResponse() .withStatus(HttpStatus.SC_OK) .withHeader("Content-Type", "application/json;charset=UTF-8") .withBody("custom response")));
Create a test that calls the defined endpoint, eg. with RestAssured: given() .when() .header("Content-Type", "application/json;charset=UTF-8") .then() .body(equalTo("custom response"));

The test fails because a file "get-data.json" is missing.


java.lang.AssertionError: 1 expectation failed.
Response body doesn't match expectation.
Expected: "custom response"
Actual: <html>

**Expected behavior**
The test should pass, regardless of existence of a file "get-data.json", as the mapping has defined body response.

As a workaround, the mock server can be created without @KnotxWiremock and then the test is going to pass.
`    protected WireMockServer mockServer;
//...
        mockServer = new WireMockServer(4000);
        mockServer.start();
`

**Additional context**
A running test with the workaround:

// @KnotxWiremock(port = 4000) protected WireMockServer mockServer;

@Test
@KnotxApplyConfiguration("some-config.conf")
public void testForBug(Vertx vertx, VertxTestContext testContext) {

    mockServer = new WireMockServer(4000);
    mockServer.start();

    stubForServer(mockServer, get("/get-data.json")
            .willReturn(aResponse()
                    .withStatus(HttpStatus.SC_OK)
                    .withHeader("Content-Type", "application/json;charset=UTF-8")
                    .withBody("custom response")));

    given()
            .when()
            .header("Content-Type", "application/json;charset=UTF-8")
            .get("http://localhost:4000/get-data.json")
            .then()
            .body(equalTo("custom response"));

    testContext.completeNow();
}
