[flaky tests] Address SIGSEGV on ResultTracker while running alter_table_randomized-test This addresses a flakyness in the alter_table_randomized-test whereby calling ResultTracker::FailAndRespond() on a transaction that was never tracked (a legal and possible thing for follower transactions) would cause a SIGSEGV. The SIGSEGV is caused because we try to deference the CompletionRecord* to track its memory, even though we already know it doesn't exist. This is hard to reproduce in either exactly once tests, but the change is pretty obvious. I also added some comment on how that can happen, it took me a while to find the path that could cause this (again).
