[BugFix]If cancelled by be add query_ctx into sc_map

[zombee0]

Why I'm doing:

in ExecEnv::GetInstance()->query_context_mgr()->remove(_query_id);
we will extend lifetime by adding query_ctx into the sc_map, we do that
for the upcoming fragments, but if query is cancelled by be, we don't
know if there are upcoming fragments, so we need skip the check on
it->second->is_dead(), and give it the second chance.

What I'm doing:
