Adjust test so that it fails for the right reasons.

Test passes if second cf-agent invokation also uses -K, which
is expected (and a crude workaround). But at least it shows that
the test is implemented correctly now.

The regex can probably be made less aggressive, but it does the job.
More verbose logging, and make the testcase pass.

Using ifelapsed => 0 in the method promise in bundle example
is necessary.
