    shell: Icon name helper returns symbolic name
    
    The helper function to get the icon name from a GIcon directly
    returns the symbolic icon now. This makes it in turn possible
    to also directly check if the theme has the icon with the symbolic
    name instead of checking of for the full colored one and then
    deriving the symbolic name from that. The latter (old) practice
    will fail if there is a symbolic icon in the theme that has no
    full color icon (like e.g. thunderbolt).
