* Removed check for invalid object in formatResult(), Title::makeTitle() always returns an object
* Don't call Title::exists() when result is not cached since the page must exist, and this was issuing a database query per row
* Reorder some variables for better clarity
* Don't execute the LinkBatch if there are now rows
* Call methods directly on ResultWrapper instead of DatabaseBase in preprocessResults()
* Use local context to get message
