Fix hunter bot losing dismissed pet during maintenance (#1286)

* Prevents recreating the tamed pet in InitPet() for hunter bots

This update adds a check to prevent the InitPet() method from re-creating a pet for hunter bots that already have a tamed pet (GetPetId() != 0). This prevents pets that have already been trained and have talents set from being lost, especially after login or teleportation. Responsibility for re-summoning an existing pet can be handled separately via LoadPetFromDB.

* Including check at start to avoid creating a new pet if the bot already has one active or saved in the stable (CurrentPet).

Initial check to avoid pet re-creation.

Selection of tamable creatures appropriate to the bot's level.

Creation, configuration and saving of the pet.

Application of visual effects and initialization of talents.

Activation of autocast for non-passive spells.

* Fix
