Title:	tracing: (self) deleted command or coroutine after exit doesn't invoke leavestep handler, so it's not paired to enterstep

Description:	Execution trace (leave or leavestep handler) will be avoided if command gets deleted during the executing and tracing process, so the leave/leavestep calls becomes unpaired to the enterstep calls (no matter how deep by nesting/recursion). The same is also valid for coroutine after its exit (what basically equal to its deletion) and probably therefore more important here, because the deletion is not avoidable in case of coro. The traces behind the behaviour lead to [571385ffffffffffffff], where the "fix" was introduced as preventive measures against a segfault, but the root of that issue was obviously different (and also already fixed now, I guess with the NRE). The fix is more or less trivial, so I'll provided it as a branch soon.

And gibhub actions tell's it's OK too! sebres added on 2025-03-19 15:12:19: There is new 8.6-based branch bug-5bd41844e6-coro-exec-trace that fixes the behaviour (see new tests). I'm waiting for a feedback... Tests and reviews are welcome.
