Add fields tests for QPaper

[Fibii]

Description

QPaper.test.js doesn't have "rendered data tests", which lead to a logic error as shown in issue #14

what should be added

two checks must be added, preferably after line 35:

expect(getByTestId('title').textContent).toBe(question.title)
expect(parseInt(getByTestId('likes').textContent, 10)).toBe(utils.getLikes(question.likes)) 

aside from that, the mocked question has 0 likes, another question should be created, that contains likes, and the component will be tested again

possible fix

create a test called "renders QPaper" that asserts that the fields are rendered properly, with 2 different questions
