task priority not saved
Steps to reproduce:
- Open GNOME To Do
- Create a task
- Set high priority to that task => the set priority appears properly through a background color change
- Close GNOME To Do
- Open GNOME To Do => the set priority is gone for the chosen task, no more background color change for that task, the default background color is back
This is on Debian stretch with GNOME To Do 3.22.1
