Describe the bug

This is just a example cause there is tons of others

       channel = await self.get_channel(thread_id)
       msg = await channel.send('ping')
       await msg.delete()

ERROR:asyncio:Task exception was never retrieved
future: <Task finished name='Task-4' coro=<Bot.keep_them_all_alive() done, defined at /Users/fpierfed/workspace/keepalive/./bot.py:58> exception=AttributeError("'NoneType' object has no attribute 'delete'")>
Traceback (most recent call last):
  File "/Users/fpierfed/workspace/keepalive/./bot.py", line 64, in keep_them_all_alive
    await self.keep_alive(thread_id)
  File "/Users/fpierfed/workspace/keepalive/./bot.py", line 72, in keep_alive
    await msg.delete()
  File "/Users/fpierfed/python_venvs/keepalive/lib/python3.9/site-packages/pincer/objects/message/user_message.py", line 583, in delete
    await self._http.delete(
AttributeError: 'NoneType' object has no attribute 'delete'

the fix for it is to add

.         channel = await self.get_channel(thread_id)
.         msg = await channel.send('ping')
+         msg._client = self
+         msg._http = self.http
.         await msg.delete()
