mangos one Hunter pet's aggressiveness setting overrides Eyes of the Beast inappropriately

Summary: When hunter pet is in defensive or aggressive mode, the player loses control of the pet while it attacks enemies automatically.

Steps to reproduce:

1. Put hunter pet in defensive mode
2. Cast Eyes of the Beast
3. While in control of the pet, move it near hostile mobs until they are aggroed

Expected result: Pet does not automatically respond to enemy attacks in any way until Eyes of the Beast is exited.

Actual result: Pet's defensive/aggressive AI overrides player control.

Proposed solution: Eyes of the Beast should take precedence and completely override any AI behavior of the pet until the spell stops being channeled.

Note: There is a possibly related issue (will file separately) where hunter pets in defensive mode will briefly attack mobs when attacked and then stop. It may be related in that it's a similar problem of the pet's AI taking precedence over other behaviors when it shouldn't.
