Bug with warlock's Enslave Demon

Current behaviour:

1. Warlocks can cast Enslave Demon, even they have not dismissed their pets.
2. Warlock cannot control enslaved demon to attack, but can let them follow, stop and use their spell.

2. Enslaved demons should be able to attcak.
3. Enslaved demons' spell should have gcd and cd.
