Code review comment for lp:~xnox/upstart/read-vs-sigchild

Haha, and it didn't:

not ok 16 - with no such file (read error)
 wrong content in file 0x55c91bf480 (output), expected 'test: Failed to spawn test (foo) main process: unable to execute: No such file or directory
' got 'test: test (foo) main process (14635) terminated with status 255
'
 at tests/test_job_process.c:1220 (test_start).
