Ops/unit test js

https://trello.com/c/GKHqmYpP/202-implement-unit-testing-for-all-fe-js

Components being tested

• Submenu (Sorin)
• Landing page header (Jesus)
• Cookies-consent (Sorin)
• Test the collapse menu (Sorin)
• Test the icons controller (only the units that are not Service dependent)

We decided not to test those anymore since they only return some kind of data.

• Animated-icons-info.service
• Eos-icons-collection.service (Richa)
• Eos-icons-info.service
• Eos-icons-search.service
• Copy to clipboard (Richa)
• when clicking on an icon we call the service and receive some response
• when the icon has no data, we still check the response to make sure we are still showing something (in this case I think we return something like "no data available"
• Maybe test the object structure of the first service call when we get the glyph.json list from the package

Note:

We cant test services at all as they rely on Node.js and Express.js being functional and accessible. We will have to do some researches for this in the future.
