tests: add test that @commands in debugcommands.py are sorted

I felt like inline Python in test-check-code.t was the most

be source file agnostic.

The test currently fails.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
