Xpra: Ticket #359: window icon goes missing when resuming

This only affects some apps (vbox, ensight,..) and only when started from another app (a terminal is the easiest way):

start a session with xterm
start VirtualBox from xterm (or other terminal app) - the vbox window has the correct vbox icon
disconnect
re-connect - the terminal window icon is correct but the vbox window uses same icon as the terminal window!?

I've tried:

disabling self.raw_window_icons so the icon would be sent with the metadata rather than after (in case it was a window setup race) - no effect
saving the window icon to file on the client side to verify that we are sending the correct one with:
```
pixbuf.save("window-icon%s.png" % time.time(), "png")
```
starting vbox directly (without a terminal) shows the correct icon every time

I'm out of ideas!

And now I can't reproduce it anymore. But before that, the prime suspect was the group-leader code.

It was a race, which explains why only some applications showed the problem some of the time.
