Create public API for accessing the root element.

This would essentially be the string argument case of -get-element, but allows other third party DOM helpers to function without needing the this context of the test to be passed in.

how is this different from getContext().element?

[rwjblue]

It isn’t, but there is some issues that folks will have to deal with there. For example, if this isn’t a test setup with setupTest, setupRenderingTest, setupApplicationTest (e.g. a plain QUnit test, or a legacy moduleForAcceptance test) doing getContext().element would result in a very obtuse error message (element of undefined or some such).
