DialogDelegate unittests: Remove dead code.

This CL removes some dead code from dialog_delegate_unittest.cc. r206950 made
the TestDialog class a ButtonListener and added the last_pressed_button()
method. However r372427 removed the last usages of TestDialog as a
ButtonListener. This CL modifies TestDialog to not be a ButtonListener anymore
and removes the associated dead code.
