Title: Bug 725954 - Use `about:credits` instead of `about:` as former one seems to break test on nighly.

Currently [tinderbox](https://tbpl.mozilla.org/?usetinderbox=1&tree=Jetpack) is orange as there is some strange issue with window when setting event listener on it. It also seems than issues only happens on about: page, using `about:credits` does not seems to have similar issues, so this change uses that url for test to make tree go green again. Proper investigation / fix can come in a separate patch.
