Week 1 , Week 2 Tickets + Functional tests

1) All tickets for week1 and week2 are completed.
2) Unit tests those were breaking down are fixed.
@Ashok-matrix By removing this signIn() and replacing it with the full steps of the login, the functional tests breaks because I don't have that same user on my database. 

If you look at the FunctionalHelper inside the test _support folder in the FunctionalHelper file, you will that the sign in helper was making sure an account existed, and if not, then it created the user in the database. We need to continue to use the ->signIn() method.
