 The call to flush_rewrite_rules() in populate_network() doesn't actually
 do much because although the lines before update the permalink_structure
 this doesn't actually change the value cached in the WP_Rewrite property.

 This means that incorrect rewrite rules are stored for the main site when
 setting up a network. NB: this only occurs when the permalink structure
 had already been set to something before installing the network.

 The fix would be to use $wp_rewrite->set_permalink_structure which updates
 the option and re-initializes the $wp_rewrite global to use the new
 structure.
