Visage birds not updating to ult level when using stone form

[ninjaox]

Summary:
on the dota 2 wiki (http://dota2.gamepedia.com/Familiar) it is stated that visage familiars' stats should update to reflect the current level of 'summon familiars' when they use stone form. They currently do not do this. I do not know if this is old information or not, but i cannot find any patch notes suggesting that this ability was removed.

Repro Steps:
1) get one level in summon familiars as visage, summon the birds
2) level up summon familiars a second time
3) use stone form as the visage birds

Result:
the birds' stats (e.g. HP) remain unchanged

Expected Result:
the birds' stats should increase to reflect the new level of summon familiars.

This affects everything which scales with ability level on the birds.

1. Health
2. Armor
3. Damage charges bonus value
4. Even Stone Form's damage and hp regen bonus

None of them update upon leveling the spell. Health, armor and attack damage should update as soon as Stone Form's buff gets applied (the one after the short root). The damage/regen bonus of Stone Form should immediately update upon leveling Summon Familiars (this was the pre-7.00 behavior).
