Picasso is empty after moving start date of a period

When changing the start date of a period, the picasso is empty when navigating back to it
- no schedule entries
- no day reponsibles
- the displayed dates are correct

I thought we would reload all scheduleEntries when navigating to picasso. Seems not to be the case anymore (no network requests triggered).

How to reproduce:
1. Open picasso
2. Go do admin and change the start date of the period by 1 month
3. Go back to picasso, the picasso is now empty
