/**
* Fix updates Joomla has already found.
*
* Joomla sometimes has a stroke and clears the extra_query column of the #__update_sites. This means that it copies
* over an empty extra_query to the #__updates table. Even though we have fixed the #__update_sites already, the
* fact that it was previously broken means that Joomla STILL doesn't see the extra query for the udpates it has
* already found, therefore trying to install them will fail with a 403 error.
*
* This method addresses this madness. It trawls the #__updates table for any updates already found with the given
* update site ID and makes sure that their extra_query matches the one it should have been using. If not, it is
* updated.
*
* If at least one update record has been updated it returns true so that refresh_update_site() can then clear the
* undocumented query caches of Joomla. If we don't do that then EVEN THOUGH we have fixed BOTH the #__update_sites
* AND the #__updates records for our extension Joomla would STILL fail to download the updates with a 403, since it
* would be using the cached updates from the undocumented query cache.
*
* The fact that Joomla was trying to tell me that somehow it's my problem that it does all these stupid things is
* unconscionable. Still, I am proving ONCE AGAIN that I can work around Joomla's major bugs, even the ones that are
* left unfixed after a decade of me reporting them privately to the project. What's worse is that my public report
* on March 6th, 2021 was met with open hostility and threats instead of the project writing the total of 10 lines
* of code to address it. This is absolutely insane. No problem, though, here I am working around Joomla's bugs, as
