e2e: script-related timeouts -> 60 seconds

Should help with cases where IE has bombed due to
angular/angular.js#10214, by failing out of
the test before SauceLabs ditches it in a way that causes protractor
to lose track of it.

At best, we may have an IE test failure that no longer hangs the entire
e2e suite until such time as Travis times the whole thing out. :)
