Problem

As part of issue #59, all snapshots tests where removed. We would now like to replace these snapshots with a more meaningful unit test.

Acceptance Criteria

Using @testing-library/react create a test for Menu.js found in src/components/Header/Menu/Menu.js

I'll take a look at this one, if that's alright?
