When you cast Bloodrage on self or another unit, then level Bloodrage up further, and then refresh the buff on self or the same unit by recasting it doesn't update the buff's damage amp and kill heal values to the new level.

Similarly, when facing an enemy Rubick, casting Bloodrage on a unit which Bloodseeker already Bloodraged, doesn't update the buff's source to Rubick, so that Bloodseeker still takes full creddits for it.

Repro 1:
1. Learn Bloodrage
2. Cast Bloodrage on self
3. Level up Bloodrage again
4. Refresh the buff on self

Result: The buff keeps the damage amp and kill heal values from the previous level.

Expected: The buff should update to the new level when refreshed.

Repro 2:
1. Learn Bloodrage
2. Cast Bloodrage on self
3. Have an enemy Rubick steal Bloodrage
4. Have the enemy Rubick refresh the Bloodrage buff on you

Result: The Bloodrage is still creddited to Bloodseeker. When cast on self, it keeps its green borders (red borders when cast on enemies).

Expected: Bloodrage should update its source to the new caster. So when refreshing Bloodseeker's buff he places on himself, and then an enemy Rubick refreshes it, it should update its source to Rubick and turn red (or green when refreshing it on an ally).
