This change makes the dots prettier during probetests
When calling the resetswift script, the probetests will use subprocess
to redirect stderr to stdout and capture stdout into a buffer. We print
the captured buffer from resetswift's combined stdout/stderr and let
nosetests stdout capturing handle printing the output for debug only if a
test fails.
