Fix sorting of integrations on Python 3.x.
Review Request #10524 — Created April 10, 2019 and submitted — Latest diff uploaded
The code to sort integrations was using the entire dictionary as a key.
This happened to work on Python 2.x, but failed entirely on 3.x. We
now use the integration name as the key instead, which is what was
Manually tested on Python 2.7 and 3.7.
Unit tests pass on both.
