Fix back button exiting app

[maelchiotti]

• Instead of closing the drawer and exiting the selection mode on the Notes page only
• When exiting a label page or the bin (Simplify routing #314)

It works fine, when I press back on the bin page, it takes me to the app's home screen (main notes list), but it still won't work on selection menu nor from the label pages.

Yes, I have trouble understanding why it won't work with the selection menu. Will look deeper into it.

However it works for me for the labels pages 🤔

Oh well no it doesn't sometimes, my bad. A never ending battle 🥲
