拼音模式應直接輸出非拼音符號

打 第 123 號，
僅得 第 號, 否則必先切換英文，才能打半型數字。

Test case:

ChewingContext *ctx;
ctx = chewing_new();
start_testcase(ctx, fd);
chewing_set_KBType(ctx, KB_HANYU_PINYIN);

type_keystroke_by_string(ctx, "pin yin  123 mo2shi4");
ok_preedit_buffer(ctx, "拼音 123 模式");

chewing_clean_preedit_buf(ctx);
chewing_delete(ctx);

@jidanni can you try this fixed version?

Pre-built binary:

• https://people.debian.org/~koster/libchewing3_0.8.4-3~3.gbp6aaa9d_amd64.deb

curl -O https://people.debian.org/~koster/libchewing3_0.8.4-3~3.gbp6aaa9d_amd64.deb
sudo dpkg -i libchewing3_0.8.4-3~3.gbp6aaa9d_amd64.deb

OK, now it works.
