Title: Fix systray icons not appearing when the program in question is first loaded

See issue #807

Something weird with cinnamon-tray-icon - I think it doesn't like having its size messed with? Not sure entirely - this seems to fix though, and I think it'll still control the problem of icons being huge when the theme doesn't properly define styles (looking at older commit against this file in git blame)
