Bug: `inspect guild` is broken

It sends the spinner message, but then runs into:

Ignoring exception in command inspect guild:                                                                                                                Traceback (most recent call last):                                                                                                                            File "/home/erin/.cache/pypoetry/virtualenvs/cabling-bot-417_n4la-py3.10/lib/python3.10/site-packages/discord/ext/commands/core.py", line 184, in wrapped     ret = await coro(*args, **kwargs)

Which appears to be due to utils.discord.guild_attributes() passing when no user parameter is passed to it.

What should happen instead, is that the user-related attributes are conditionally added to the guilds array dependent on the user parameter, and if the guilds array is empty, to return None.
