[GAMEPLAY] Azir turret doesn't lose focus

Just played Azir in a fun game and saw that his turrets doesn't lose the focus if the target doesn't die.

Example how it occured:

• Enemy champion in range of tower ruin
• Place Azir turret onto this ruin
• Tower focuses enemy champ and shots once
• Enemy champ leaves tower range and the red turret-focus-line sticks to this champ

This stays until the enemy champ is killed.
