Remove code folding and raw log output

Code folds were interacting poorly with Travis and causing output to be
lost. This was causing xcresult log output to be lost.

Travis terminates jobs that exceed its maximum log output length, so
showing raw log output could cause failing jobs to be killed for
unrelated reasons.
