Avoid crash in language_info
language_info calls:
show_language_command (NULL, 1, NULL, NULL);
... "knowing" that show_language_command does not use its ui_file
parameter. However, this was changed in commit 7514a661
("Consistently Use ui_file parameter to show callbacks").
This patch changes language_info to pass a ui_file.
It took a while to write the test -- this function is only called when
'verbose' is on and when switching the "expected" language in auto
mode.
