Stop using org.keycloak.quickstart.test.TestsHelper

[jonkoops]

As part of #584 the code for the test helpers was moved into the quickstarts. However, the TestsHelper has been deprecated and is still used. This deprecated code should be removed.

Would I be able to be assigned to this issue?

Sure, go right ahead.

Hi. I and other students from FIU are working on resolving issues of keycloak. My team member, ATurt275 (https://github.com/ATurt275), was already assigned on one issue, but we need to be assigned as a Team, so I wanted to ask is it possible if you will add two more accounts: nnniyaz (https://github.com/nnniyaz) and alexandravsmith (https://github.com/alexandravsmith) on issue #597

If you want people to be assigned make sure that you comment in this thread, otherwise we cannot add their handle. When providing a PR I suggest you create a commit with multiple authors if you want everyone to be attributed.
