core: parse_to display name multi-token no-quotes fix

Fix for properly returning a non-quoted display name that is
composed of several tokens (contains spaces). The previous version
would set the display name to the first token, in this case
(e.g. Foo Bar <sip:foo at bar> resulted in display_name="Foo" instead
 of "Foo Bar").

Closes FlySpray#39 .
(cherry picked from commit 907686c0c4c1141af175d692251b8e1fab28b64e)
