tdf#152459: fallback to language-only when looking for grammar checker
LanguageTool registers itself for languages like "en-US", "es-AR", "de-DE";
but also for generic "en", "es", "de". When the requested language, like
"fr-CH" or "es-PH", is not found in the registered grammar checkers, the
fallback strings will be attempted.
