Bug fix - failing CI test

[marko220991]

After taking a closer look at failing CI test, some changes were made and now all tests are working fine.
Some builtin PHPUnit functions, like assertContains and assertInternalType, were depracated, and that is why we had warnings and failures.

After we updated those php files with new functions, all seems to work fine now.

• Instead of assertContains we used assertStringContainsStringIgnoringCase();
• Instead of assertInternalType we used assertIsArray();
