Duplicate mocks in JS tests

[igorschoester]

• [x] I've read and understood the contribution guidelines.
• [x] I've searched for any related issues and avoided creating a duplicate issue.

Please give us a description of what happened.

When running Jest tests I get duplicate manual mock warnings for:

• fileMock.js in Free and yoast-components.
• i18n.js in yoast-components and search-metadata-previews.

Full output

``` jest-haste-map: duplicate manual mock found: Module name: fileMock Duplicate Mock path: /Users/igorschoester/vagrant-local/www/wordpress-default/public_html/wp-content/plugins/wordpress-seo/javascript/packages/yoast-components/jest/__mocks__/fileMock.js This warning is caused by two manual mock files with the same file name.
