Hotfix: version fix on python-engineio to debug uWSGI socket issue

[okayhooni]

fix: https://github.com/pinterest/querybook/issues/1319 related to: https://github.com/miguelgrinberg/python-engineio/issues/330

python-engineio (version between v4.5.1 and v4.7.0) has some bug on socket close logic.

Due to this issue, Querybook webserver got the error below all the time.

Traceback (most recent call last):

This issue has been solved by python-engineio version 4.7.1 (released just 5 hours ago).

I deployed and tested Querybook with this version, and the issue was solved.

@okayhooni looks like querybook doesn't directly depend on python-engineio. And I checked the version of python-engineio when running make, it is python-engineio 4.9.0. Is it still an issue on your end if without this PR?
