[YouTube] Fix channel ID extraction of YouTube channel RSS feeds

Browse source 
The yt:channelId element doesn't provide the channel ID anymore and is empty,
like the id element, so we need now to extract it from the channel URL provided
in two elements: author -> uri and feed -> link.

Also avoid a NullPointerException in getUrl and getName methods.
