Add RemoveAurasWithInterruptFlags call before all TeleportTo operations
to prevent race condition crash in battlegrounds.
The crash occurs when area auras (like "Entering Battleground") are
queued for removal in Aura::UpdateTargetMap's targetsToRemove list,
but the unit is deleted before the 500ms update cycle completes,
causing SIGSEGV when accessing the dangling pointer.
This fix removes auras with AURA_INTERRUPT_FLAG_TELEPORTED and
AURA_INTERRUPT_FLAG_CHANGE_MAP before teleporting, matching the
behavior in Player::TeleportTo for real players.
Affected locations:
- BattleGround join/teleport
- Spirit healer/graveyard teleport
- Corpse resurrection teleport
- Meeting stone teleport
- Master follow teleport
- RPG unstuck teleport
- Random bot teleport
- Chat command teleport
Raid-specific teleports excluded as they require separate testing.
