Support failed authentication, too

[SchulteDev]

This extension supports responding with a "problem"

• if an authentication if required, but not given, see UnauthorizedExceptionMapper
• if a valid authentication is given, but role is forbidden to access the requested resource, see ForbiddenExceptionMapper

There is one more case:

• A resource requires authentication, an authentication is given, but invalid.
  Imagine one more test in TestResourceIT:

@QuarkusTest
public class TestResourceIT {

   ...

  @Test
  void restrictedAuthenticationInvalid() {
    given()
        .auth()
        .preemptive()
        .basic("scott", "wrongpass")
        .when()
        .get("/test/restricted")
        .then()
        .statusCode(UNAUTHORIZED.getStatusCode())
        .body("status", is(UNAUTHORIZED.getStatusCode()));
  }

For time being, this extension seems not to catch this case, an empty body (401 HTTP status code) is being returned.

Feature request
Please add to this extension, that if a given authentication is invalid, a valid API "problem" will be returned.

I've noticed that too. I'm gonna go check it out.
