Tests untruly failing if screenshot taking is still in progress during test shutdown (ECONNREFUSED)

[bentolor]

I get sporadically the following errors on using protractor-screenshot-reporter:

node_modules/protractor/node_modules/selenium-webdriver/http/index.js:136
      callback(new Error(message));
               ^

Fatal error: protractor exited with code: 1

Obviously the issue is that the Jasmine/Protractor-Tests already are shutting down and therefore the PhantomJS process terminates while the screenshot taking is still in progress.

In my opinition screenshot reporter should fail silently & gracefully instead of pulling the test itself into damnation here.
