extensions: fix up many many debug logs that use %r

This gets us a bunch closer on Python 3, but I'll still have to use a
ton of sad globs. A previous version of this patch tried to preserve
the %r formatting, but upon review Yuya noted that special characters
in extension names is very unlikely, so we can just use %s and not
sweat the quoting.
