In 1.1.2 last sparkle item picked instead of latest

[andrewzirkel]

Describe the bug
In 1.1.2 when processing a sparkle feed with multiple items the last item in the feed is picked instead of the latest version. This results in an error if the last item is not available. In 1.1.1 the latest versioned item is picked.

To Reproduce
Consider this feed: https://www.kutasoftware.com/updates/appcast_a1m.xml
1.1.2 downloads the last item in the feed instead of the latest version
This failed since the last item is no longer available

Expected behavior
The latest version should be downloaded if there is version information.

Desktop (please complete the following information):

• macOS: 10.14.5
• Recipe Robot Version: 1.1.2
• which python: /usr/bin/python
• python --version: Python 2.7.10
