Change Details

`Flow\Parsoid\Utils::htmlToPlaintext` does what `Sanitizer::stripAllTags` already does & we should probably re-use that instead of inventing the wheel. `Flow\Parsoid\Utils::htmlToPlaintext` also truncates. We can either keep `htmlToPlaintext` around & make it call `Sanitizer::stripAllTags` (instead of stripping ourselves) & `Language::truncate`, or get rid of `htmlToPlaintext` altogether & call both of those wherever we're currently calling `htmlToPlaintext`
