Cleanup (A113)

If not composing a word, then consideredWord is always the empty
string.
Hence, it's never whitelisted, but it's also always "NotAWord",
so isWhitelistedOrNotAWord returns always true, so
allowsToBeAutoCorrected is always true. Which means that
isPrediction implies allowsToBeAutoCorrected == true.
Thus, !isPrediction && !allowsToBeAutoCorrected is strictly
equivalent to !allowsToBeAutocorrected.
