Protractor 24.1 updates.

[Droogans]

Astrolabe uses Selenium's raw findElement, which return WebElement objects.

Protractor 24.1 introduces a new ElementFinder object, which behaves differently.

Astrolabe should support both, but prefer the new ElementFinder type by default.

As of this writing, they are still polishing the final implementation, so action isn't needed at this time.
