Teste de criar novo usuário retorna Failure quando na verdade deveria retornar Success

Olá, pessoal, fiquei um tempo sem mexer no projeto e tinha parado na parte aonde refatoramos o código para o padrão Page Objects. Estranhamente, apesar de que na página existe um usuário com o nome e o e-mail informado e até mesmo do debugger eu validei que a informação vem como true para usuário existe, o JUnit está marcando o teste como Failure na asserção.
