#17 UpdateDB crashes when finding unknown format

[Henrik Wejdmark]

When UpdateDB finds an mp3-file with a unknown tag-
format, it tries to handle it but calls a "break" even
though the script is not running within a while loop.

This patch changes the break into an if-else but doesn't
solve my actual problem with some MP3:s. I'll try to dig
deeper into why the ID3-tags can't be read.
