Remove the unused method to retrieve patches from events

[veruu]

While the events API from Patchwork2 got some speed enhancements, the stability wasn't tested. We already have a working and stable interface via the patch API and don't have use for two of them (and the events interface would require some modifications to only retrieve series-completed category etc.)
