With the changes to EditorSpellCheck::SetFallbackDictionary to use a
promise chain to support calling either SetCurrentDictionaryFromList or
SetCurrentDictionaries as required, it is now possible that
RemoteSpellCheckEngineChild is destroyed by the time the second promise
runs. During destruction, RemoteSpellCheckEngineChild calls
mozSpellChecker::DeleteRemoteEngine, which sets mEngine to nullptr.
This patch adds a nullptr check for mEngine in both
SetCurrentDictionaryFromList and SetCurrentDictionaries.
