Parameter set as endpoint in integration test

Description

In ServiceIntegrationSteps.java line 208 the parameter account_id=1000000 is set using .setEndpoint(). This will not work when upgrading eiffel-commons to the latest version. To be able to run integarion tests after updating eiffel-commons version the account_id parameter must be set using addParameter method.

Motivation

Integration test will not work if eiffel-commons is updated to latest version.

Exemplification

Make the code look more decent.

final HttpRequest requestLogin = new HttpRequest(HttpMethod.GET, httpExecutor);

requestLogin.setBaseUrl(GERRIT_BASE_URL)
            .setEndpoint("/login/")
            .addParameter("account_id", "1000000")
            .addParameter("http.protocol.handle-redirects", "false");

final ResponseEntity response = requestLogin.performRequest();
