Double output on error

[prencher]

I'm seeing some weird double output with version 0.5.3 (parcel 1.5.1). It happens with both parcel index.html and parcel build index.html, but it seems less frequent with build.

Minimal reproduction: https://gist.github.com/prencher/73cc11f5a8a0701e8960f04fa22f2e4e

Example output:
