[Bug] Error if no feed item

[coolacid]

If there is zero feed items the plugin will error out

[abaykal]

This is still the issue with the version 1.4. if I have multiple input feeds in one config file for multiple feeds, if one of the feeds is empty, the entire plugin crashes.

old issues followup: this definitely like a breaking condition which renders the plugin somewhat unusable which is also easy to fix.

I tested this behaviour with

<?xml version="1.0" encoding="windows-1252"?>
<rss version="2.0">

</rss>

actually an empty feeds, but still with some description and the plugin is still up and working as of the current version.

what I do believe is that the problem is when the rss feed is not valid 'because

feed = RSS::Parser.parse(body)

is actually performing a validation and should be like this, if the feed document is not valid, we should log the error.
