Messes up the single line output for example karma test run

[chrisprobably]

When using grunt-hub to run karma tasks in Gruntfile's in sub projects it prints the output differently to how you would see it if you ran that Gruntfile on the command line.

For example, when performing a karma test run using grunt-hub I get the following printed to stdout:
