Remove old TODO

It was added in f7fe87dd4e when I rewrote
window functions to include more infos (not just char* but whole jid
struct I think).
The same todo was added to win_print_outgoing_muc() but removed in
f3d9de133e.

This TODO should have been removed in
f3d9de133e since there we added the myjid
parameter.
