This is a follow-up of rails#35310. Currently `Topic.find_by(id: "not-a-number")` matches to a `id = 0` record. That is considered as silently leaking information. If non numeric string is given to find by an integer column, it should not be matched to any record. Related rails#12793.

Related to rails#35336. The notable thing about rails#41516 is that unknown labels will no longer match 0 on MySQL. Matching unknown labels to 0 was not by design, but rather almost like a bug, people should not rely on that behavior. Closes rails#41595.
