mbc logs command is broken

[psrpinto]

The mbc logs command fails with the following error (full stack trace at the end):

TypeError: create_task() got an unexpected keyword argument 'loop'

Steps to reproduce:

# clone repo
git clone git@github.com:maubot/maubot.git

# install latest python 3.8
pyenv install 3.8.13

# create virtualenv
virtualenv -p ~/.pyenv/versions/3.8.13/bin/python .venv

# install dependencies
pip install --editable .

# run command
mbc logs

Full stack trace:

  future = asyncio.create_task(view_logs(server, token), loop=loop)
