MobileFrontend SpecialMobileEditWatchlist file has flawed logic when it comes to retrive the PageImages.

The executeViewEditWatchlist() function first calls a SpecialMobileEditWatchlist::images hook to retrieve all page images for current query (PageImages extension listens to that hook and returns an array of images), then for each Article it:

• if the image exists in the $images array - use it
• otherwise call PageImages::getPageImage() to get the image

Most probably the call to the PageImages is not necessary, as we already asked PageImages for image for given article and it just doesn't exist. There is no need to do the SQL query once again.

Is there any special case, where we have to execute PageImages::getPageImage()? If no, we should get rid of that code.
