Get rid of the white flash when the app starts up (#3083)

* Prevent FOUC on startup, use Signal Blue instead Instead of flashing a white background on startup, the app will show a blue background while everything is loading. * Make sure tests are rendered on white background * Use `icon_250.png` as the loading image * Remove hardcoded 'Loading...' text from template
