URL: https://github.com/apache/airflow/issues/19612
### Apache Airflow version

### Operating System

### Versions of Apache Airflow Providers

### What happened
When I mark a defferd task to Failed-State then clear it or clear a defferd
task which in Defferd-State, this task is marked success immediately.
I check the task instance table, this task's next_method is not null when I
clear this task.This cause task's execute function is replaced by next_method
function.
### What you expected to happen
When I clear a defferd task, I want to re-judge it's trigger condition,
re-execute the execute function.
### How to reproduce
Sensor
``` python
class ExternalTaskFromOtherAirflowSensor(BaseSensorOperator):
def execute(self, context):
trigger = ExternalTaskFromOtherAirflowTrigger(args)
self.defer(trigger=trigger, method_name="execute_complete")
def execute_complete(self, context, event=None):
return
```
Trigger
``` python
class ExternalTaskFromOtherAirflowTrigger(BaseTrigger):
def _get_task_instance_state(self):
sql_query = "SELECT state FROM {}.task_instance WHERE dag_id = '{}'
and run_id like '%{}%';".format(
self.old_airflow_db_name,
self.old_external_dag_id,
self.old_external_task_id,
self.old_external_execution_date_str
)
async def run(self):
while self._get_task_instance_state() == False:
await asyncio.sleep(5)
yield TriggerEvent('success')
```
1. Clear this task when it is in **defferd** State.
2. Mark this task as **failed** and clear this task.
Both operations above will cause this task is marked as **success** instead
of re-execute the execute function.
### Anything else
Similar issue:
#18146
#19120
I try to add this code in **models/taskinstance.py clear_task_instances
function**
