   **What happened**:
   
   <!-- (please include exact error messages if you can) -->
   Smart Sensor TI crashes with a Runtime error. Here's the logs:
   ```
   RuntimeError: dictionary changed size during iteration
     File "airflow/sentry.py", line 159, in wrapper
       return func(task_instance, *args, session=session, **kwargs)
     File "airflow/models/taskinstance.py", line 1112, in _run_raw_task
       self._prepare_and_execute_task_with_callbacks(context, task)
     File "airflow/models/taskinstance.py", line 1285, in _prepare_and_execute_task_with_callbacks
       result = self._execute_task(context, task_copy)
     File "airflow/models/taskinstance.py", line 1315, in _execute_task
       result = task_copy.execute(context=context)
     File "airflow/sensors/smart_sensor.py", line 736, in execute
       self.flush_cached_sensor_poke_results()
     File "airflow/sensors/smart_sensor.py", line 681, in flush_cached_sensor_poke_results
       for ti_key, sensor_exception in self.cached_sensor_exceptions.items():
   ```
   
   
   **What you expected to happen**:
   
   <!-- What do you think went wrong? -->
   Smart sensor should always execute without any runtime error.
   
   **How to reproduce it**:
   I haven't been able to reproduce it consistently since it sometimes works and sometimes errors.
   
   **Anything else we need to know**:
   It's a really noisy error in Sentry. In just 4 days, 3.8k events were reported in Sentry.

   Any relevant logs to include? Put them here in side a detail tag:
