Terminal warnings control

[lrdossan]

With tornado version 6.2 there are some warnings on the terminal when running the tests:

/Users/user/.pyenv/versions/3.9.6/envs/cara/lib/python3.9/site-packages/pytest_tornasync/plugin.py:67: DeprecationWarning: clear_current is deprecated
    loop.clear_current()

My guess is that this warning is coming from

pytest-tornasync/src/pytest_tornasync/plugin.py

Line 67 in 9f1bdee

loop.clear_current()
