Attribute error when checking for permissions with has_permissions

[Mihitoko]

Summary

When inviting bot only with applications.commands scope has_permissions will fail due to an attribute error.

Reproduction Steps

Register a command with @has_permissions(administrator=True) for example.
Invite the bot only with applications.commands scope.
Try to execute the command.

See how you get an attribute error in the console.
AttributeError: 'PartialMessageable' object has no attribute 'permissions_for'

Minimal Reproducible Code

import discord
from discord.ext.commands import has_permissions

bot = discord.Bot()


@bot.event
async def on_ready():
    print(f"We have logged in as {bot.user}")


@has_permissions(administrator=True)
@bot.slash_command(guild_ids=[guild_id])
async def hello(ctx):
    await ctx.respond("Hello!")


bot.run("TOKEN")

Expected Results

We should get a more telling error message that the channel was not cached and for that reason we cant check permissions.

Actual Results

We get an error
AttributeError: 'PartialMessageable' object has no attribute 'permissions_for'

Since we did not get an GUILD_CREATE event for the guild because it was not invited with the bot scope

Inviting bots only with app command scope is meant for http interaction bots normally.

While this is true in my opinion there should still be a type check.

The type hints explicitly say that this can be a PartialMessagable.
Of course its a very niche problem but imo still worth to fix.
