Earlier lowercased strings were being used with the purpose
of isValid checks (spelling does not consider casing for spell
checking calls). But for showing these in suggestion, we need the
raw strings.

Note: PersonalDictionaryLookup#getWordsForLocale is used to feed
the personal LM in PersonalLanguageModelHelper.

There should be 1 executor each for static and dynamic language models.
This prevents too many dynamic LM updates from running in parallel,
competing for resources.
