Blocked damage is not counted as being "prevented" for recoup effects

The passive "Made to Last" and the unique chest "Wandering Reliquary" do not consider blocked physical damage to be prevented. Very easy to reproduce by going into a map with no life regen and blood mage. Cast a spell to lower your life and then block some physical attacks, no recoup happens. This doesn't really make any sense and is also inconsistent with the in-game tooltip for block which explicitly states that it "prevents" damage
