Land on notes list after logging in

To reproduce:

1) Click Settings
2) Log out
3) Log in
4) The sidebar is open with the content faded out

I think you should land on note list with the sidebar closed.

To solve this, I've been thinking that we should close the sidebar when the Settings button is clicked. I think it's a better flow — after fiddling with any of the settings, you want to go straight back to the notes list.
