Autocomplete callbacks can't be methods of classes

[Luc1412]

Summary

If the automcomplete

Reproduction Steps

1. Create a Cog
2. Implement a command with an autocomplete option
3. Implement the callback into the cog or any other class

Minimal Reproducible Code

class Example(commands.Cog):
    async def _example_autocomplete(self, ctx: AutocompleteContext):
        return []

    example_option = discord.Option(str, autocomplete=_player_name_autocomplete)

Expected Results

The class reference should be filled like in command callbacks.

Actual Results

Exception in event: on_interaction

Traceback (most recent call last):

Additional Context

As an alternative, you can put the callback outside of a cog. This would cause that you can't access the bot, cog, or any other useful reference.

I can reproduce this.

A possible fix would be adding self.callback.__self__ as first parameter if the function is in a class at https://github.com/Pycord-Development/pycord/blob/master/discord/commands/commands.py#L541

I'm not sure if this is related but whenever I try to use an autocomplete I get this error

TypeError: Autocomplete callback must be a coroutine.

Here is my code

@staticmethod
async def num_picker(ctx: ApplicationContext) -> Iterable[int]:
    """Return a list of random integers."""
    return [random.randint(1, 100) for _ in range(25)]

@slash_command(guild_ids=settings.dev_guild_ids)
async def num(
        self, ctx: ApplicationContext,
        extension: Option(int, autocomplete=num_picker)
 -> None:
    await ctx.respond(extension)

 -> None:

    await ctx.respond(extension)

You used a staticmethod, which should run like a normal function. Also we're thinking about making autocomplete accept sync functions.

This has been fixed, let me know if there are any issues.
