Improve stability - investigate timeouts

[juliemr]

Travis/Sauce occasionally falls over and everything starts timing out. This thread is the open investigation of whether anything can be done.

Example:
https://travis-ci.org/angular/protractor/builds/25374230

I suspect this has something to do with getting about:blank - there are occasional reports of selenium historically having issues with this (https://code.google.com/p/chromedriver/issues/detail?id=23, https://code.google.com/p/chromedriver/issues/detail?id=502)

Changing to using a data URI worked but is not supported on IE.

Update: have added more logging for sauce connect. Still seeing the issue occasionally. In contact with SauceLabs.

Removing milestone as this is an ongoing priority but not directly protractor related and shouldn't block release.

See #1051 and #1052, which are more specific issues.
