wayland: xdg-surface-configure: refresh terminal

Browse source 
Any changes done in any of the configure events are ignored before
we've ack:ed the configure event.

In particular, this means the resize done in xdg-toplevel-configure
isn't displayed until the next time we call render_refresh().

Unless we do something ourselves, this can take quite some time, since
we're basically need the slave to write something.

So, in xdg-surface-configure, *after* having ack:ed the configure
event, call render_refresh() to make the changes done in
xdg-toplevel-configure visible as soon as possible.
