System automated testing : Covering the US of Sprint 3

The goal of this issue is to cover all user stories of Sprint 3 with system automated testing (e2e). This will be done on the following branch:

Here are the user stories to cover:

[x] US-12 | As a user, I want to be able to select a destination building by clicking on it.
(NOT COVERED) US-14 | As a user, I should be able to set my current position as the starting point.
[x] US-15 | As a user, I want to be able to view directions on the map.
[x] US-16 | As a user, I would like to be able to be given directions between campuses
[x] US-18 | As a user, I should be able to choose “walking” as a means of transportation.
[x] US-19 | As a user, I should be able to choose public transport as a means of transportation.
[x] US-20 | As a user, I should be able to choose “driving” as a means of transportation.
[x] US-26 | As a user, I would like to be able to set a room as my start or destination
[x] US-27 | As a user, I would like to navigate from my desired start point / current location to my desired destination.
[x] US-28 | As a user, I would like to show the shortest path possible between my start and destination point.
[x] US-31 | As a user, I would like to be able to generate directions to rooms between floors.
[x] US-37 | As a user, I would like to navigate through building floors
[x] US-40 | As a user, I should be able to choose “biking” as a means of transportation.

Every time a user story is covered by the tests, it will be crossed from this post.
