tests: add a comment that we're purposely testing py2 extension attributes

Avoid someone unknowingly removing test coverage.  There are tests for a
properly byteified `testedwith` a few lines down.  I don't see similar for
`buglink`, but it's a trivial conversion to bytes, so I'm not concerned about
testing the expected/wanted extension state.

# A portable replacement for 'seq'

# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
