Apply language settings from _common.yaml in slot combination tests

The lang_resources fixture builds its intents dict by hand and reads only
skip_words from _common.yaml, so settings is dropped. Eight languages are
therefore tested under a configuration Home Assistant never uses:
zh-CN/zh-HK/zh-TW declare ignore_whitespace, and cs/de/ne/nl/vi declare
filter_with_regex, but both fall back to the hassil defaults.

common_dict is already loaded on the preceding line.
