rio: fix wrong frame colors when moving non-current window

When a window is moved or reshaped, that implicitely tops
the window and makes it current. The conseqence of this
is that we always have to redraw the window as if it where
a current window in any case. This was handled for Reshaped
windows, but not when the window was just moved. We now
handle both cases the exact same way, getting rid of the
Moved wctl message.
