fix: memory leaks (surprisingly a lot)

can't believe i forgot to remove some elements....... especially in the query plugin, which is used A LOT by the tracked core, wows.......
most of the leaks are caused by me not clearing the transactions IDs map, back in the days i didn't even know i have to do those since i didn't know i have to manage memory stuff
