I am trying to convert jetstream to wprgo and getting an error about "--inject_scripts=" flag when trying to run the converted benchmark.

There seems to a bug in _ReplayCommandLineArgs. When self._make_javascript_deterministic is false the function is adding "--inject_scripts=" flag without adding a script to inject.

I am at chromium revision dd2223 (catapult 9e69c3).
