org-mac-link.el: Tweak AppleScript to grab Mail.app messages

* contrib/lisp/org-mac-link.el (org-as-get-selected-mail): Make sure
no extra new line is present in the string returned from the
AppleScript.

* contrib/lisp/org-mac-link.el (org-mac-message-get-links): Get rid of
the enclosing quotes before splitting the string.
