Subject: [PATCH] st-icon: Null-check for shadow_spec before trying to paint a
 shadow

The value of priv->shadow_spec can be NULL at the time an icon is
going to be paint (e.g. because of a change in style), so we need
to check it's a valid one before using it in st_icon_paint(), as
it's already being done in other parts of the code.

Closes: #36
