[panel] Handle async load of icons correctly

Fading the application icon required the texture to have already been
loaded, which was normally the case since we create icons for apps
in the well and browser; but when finding an app not from there,
the cogl-texture for the icon might not be available.

Fix this by watching for the texture and fading when it appears.
