I'm not suggesting that you re-fix by following the example given because, well, it isn't really a problem for you to fix. It is/was something that the zencart team needed to take care of. For your part all you need do is ensure that you didn't miss anything with you upgrade (as it appears is the case)

Regarding who to "fix" the issue, the current release of ZC 1.5.4 did not have this additional variable to pass (last modification date in github was sometime middle of last year for this one file.) The remaining plugins discussed that modify the same file are in various stages of "design" and the code of which may not have been published to the plugins area. Therefore the ZC team may not have been in a position to monitor that additional code addition.

It would be helpful still though to identify which plugin and from where it was obtained had that additional assignment &$this so that it can be corrected for anyone else that comes across the issue.
