Cleaned LMS error reporting.

Even upon successful rescan, the code would throw a keyerror back. Not certain why, but LMS sends some really weird unicode JSON back as its result, unlike XBMC, so having response[0]['result'] will always throw back a keyerror.

Removing the key, however, and just asking the return to find 'result' works fine.
