run-tests: avoid an early return

To fix the "python3 pointing to python2" we will also need to create a "python"
pointer. So we will need to create multiple pointer. So we need to stop using
early return.

We replace the early return with a loop and a continue, since the next
changeset will introduce that loop anyway.

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