"run" command no longer works for PhantomJS

[roelrz]

The following commands work:

venus foo.js -n
venus foo.js,bar.js -n
venus foo.js bar.js -n
venus folder1 -n

However, the following commands no longer work:

venus run -t foo.js -n
venus run -t foo.js,bar.js -n
venus run -t foo.js bar.js -n
venus run -t folder1 -n

This issue only exists when running tests in PhantomJS (works fine when running tests in local browser)
