Evince does not save changes to settings like zoom level etc

The Evince snap does not save changed settings.

To reproduce:

  1. Run Evince and change the zoom level from the default 37.5% to 50%. Save change using Save Current Settings as default. Close snap. Run again and it’s back to 37.5% zoom. The same happens with any other changed setting, say, running in full screen mode by default.
