Wolves can't be spawned with modified max health attribute

When spawning a wolf with entity data that modifies "max_health" it does not spawn with the correct attribute base.

for example

/summon wolf ~ ~ ~ {attributes:[{id:max_health,base:200d}]}

will still spawn with the standard 8.0d base.1

This issue only occurs when a wolf is summoned without an Owner tag; otherwise, the attribute is set properly.
