Add redirect when creating a notebook when creating a task

[martineizayaga]

The user can create a notebook when they are creating a task. When the notebook is created all the user gets as feedback is a toast notification at the bottom. If the user misses this it can lead to creating the notebook again, making another notebook of the same name (that's what happened to me.)

The app should probably redirect back to the create note page when the notebook is created.

Hello ! Thanks for the report. That was the expected flow but it wasn't well implemented. There's actually #117 that's gonna do just that (among other things).
