Fix `org-babel-result-end' command to provide consistent result removal where result is type `wrap'.

* lisp/ob.el:

Fix `org-babel-result-end' command to provide consistent result
removal where result is type `wrap'. Prior to this fix
multiple (org-ctrl-c-ctrl-c) commands will add multiple newlines to
the end of results (one newline per block execution).

This fixes the test `test-ob/org-babel-remove-result--results-wrap'

* testing/lisp/test-ob.el:

Uncomment test since it now passes.
