Fix crash when OS screensaver started before opening Wholphin (#1285)

## Description
If the Wholphin OS screensaver starts before Wholphin (the app) is
opened, a default image loader is used. Then when Wholphin is opened, it
will crash when trying to set the app's image loader.

This PR adds configuring the image loader to the screensaver as well. It
is safe to do this multiple times. It's only an error to try to replace
the default image loader.
