server: fix red_current_flush to flush only the surface that was given as parameter

A side effect of the previous red_current_flush, which flushed all the surfaces, and was called on a new display channel connection, was
that red_handle_drawable_surfaces_client_synced sent the most updated surfaces images when needed. However, now, it should
explicitly call red_current_flush.
Moreover, since red_current_flush was called on a new display channel connection only if there was a primary surface,
if the connection of the display channel occurred at the moment of no primary surface, red_handle_drawable_surfaces_client_synced was buggy.
