Display errors if file does not exist

When executing:

./run-headless-chromium.js i-do-not-exist.html

It just starts Chromium and keeps waiting. I would expect it to throw an error and stop waiting.

run-headless-chromium just starts Chrome and quits Chrome if any page prints "All tests completed!" to the console. That's about it.

If you want to debug file loading issues, then you could activate verbose logging:

LOG_CR_VERBOSITY=. ./run-headless-chromium i-do-noth-exists

If that is a bit much, then you can also filter messages using Chrome's --vmodule flag. E.g. with Chromium 47.0.2526.80, I get the following message:

$ LOG_CR_VERBOSITY=. ./run-headless-chromium/run-headless-chromium.js --vmodule=*/navigator_impl.cc=1,*=0 /tmp/non-existent

Starting Chromium...
VERBOSE1:navigator_impl.cc(168): Failed Provisional Load: file:///tmp/non-existent, error_code: -6, error_description: The file or directory could not be found., showing_repost_interstitial: 0, frame_id: 1

Would it be an idea to automatically log these errors in run-headless-chromium? Because for this you need to have deep knowledge of Chromium flags, which you can not expect from someone who simply wants to see debug errors of his app.
