Add handler back to create new contact button

It was accidently deleted in a clean up CL.
Also remove the override for configureAdapter since
setEmptyListEnabled is default true in the base class.

Test:
Tapped INSERT_OR_EDIT intent from the test app and verified
tapping create new contact loaded up the editor.
