Fix red background issue with buck project output.

Summary:
Pretty straightforward. The intellij.py command was run with a console with
ansi enabled, which meant the output was wrapped in bash color codes which
were passed down to the main buck command console's stdout.

Test Plan: run buck project, no more blood bath.
