This is needed before we can upgrade to flake8 3.3.0, as that version starts flagging these errors.
These files were modified by running:
autopep8 --select E305 --in-place -r <dir>
on the affected directories. I did it one dir at a time and verified the result after each.

This patch enables flake8 rule E713:
"test for membership should be 'not in'" in toolkit/components/telemetry
by removing the relative E713 entry from toolkit/components/telemetry/.flake8
and fixing the files for which the E713 error was reported.
Precisely 6 errors violating E713 rule were found and solved.
