apscheduler.jobstores.base.ConflictingIdError: 'Job identifier (test) conflicts with an existing job'
报错原因：主要是 apscheduler 再将任务存储倒mongodb的时候是直接插入 并且任务id 就是任务名 导致 相同的任务插入错误
修改前：第84行的函数
def add_job(self, job):
try:
self.collection.insert_one({
'_id': job.id,

})
except DuplicateKeyError:
raise ConflictingIdError(job.id)
修改以后：
def add_job(self, job):
try:
if not self.collection.find_one({'_id': job.id}):
self.collection.insert_one({
'_id': job.id,
'next_run_time': datetime_to_utc_timestamp(job.next_run_time),
