fix: hitting enter after setting password redirects to demo page

[andremralves]

Closes #29

• At the bootstrap page, when the user sets the password and press enter or even when the password field is empty, he is redirected to the demo page.
• I used the "onEnter" prop from the Input component to trigger the "onSubmit" function whenever the user presses enter within both password input fields.

Before changes:

• The user is redirected to the demo page after pressing enter.

After changes:

• The user is redirected to the files page after pressing enter.

• In this screen record I fill the password fields and then I press enter. Now the user is redirected to the files page.
• I also tested pressing enter with empty fields and with just one filled.

I've pulled this down locally to check the behaviour and everything looks good. Thanks @andremralves!
