test(popover): adiciona testes para branch cornerAligned no método open

Adiciona testes unitários cobrindo o trecho de código que calcula
a largura dinâmica do popover quando cornerAligned é true e width
não é definido via input. Cobre o requestAnimationFrame e a
atribuição de widthPopover.

Fixes DTHFUI-12554
