feature: create login page

[GuilhermeLLS]

What is this

• This PR creates the login page and logic for the template.
• Add tests and stories for some componentes/pages.
• Fix miragejs server error

How to test

You can run the app and mess around with the login form, run the tests and the stories.

Observations

I had to force babel-loader version in template.json because storybook and react-scripts were in conflict due to babel-loader version.

1. Should I test components such as Input and LogginWrapper? They do not have any functionality at all, they are just pieces of UI.

No.

2. Are we going to have any UI sketchs to be used as guides? My UI skills are really bad hehe
