The Xbox's postgame map select wrappers already carry
main_menu_if_no_history, with which the stock event code calls
main_goto_main_menu() when Back closes the last screen. The PC menus'
connected_map_select_wrapper, which menu_tags.c opens in their place,
was given the same flag by tools/port_settings.py in 4301ca88d, so the
hard-coded names and the network_game_abort() call in
widget_instance_go_back_to_previous were not needed, and they changed
stock split-screen behaviour (a split-screen game is a local server).
widget_instance_go_back_to_previous is as it was before 7d128e1bd.
Checked: the harness and touch menu tests (491 passed), test_web_build
(11 passed), ui_widget.c compiled for Linux and the Android guest.
