[GAMEPLAY] Heimerdinger Invincible Turrets

Bug Desctription: I recently played a match with a Heimerdinger in lane with a Tahm Kench. Tahm would eat the Heimer turrets and upon spitting them out, they would be temporarily invincible. Attacking them was possible, but would do no damage. The turrets were still able to damage myself and Tahm, however. For about 10 seconds, the turret would take no damage from any source, and would continue dealing damage.

Replication: Tahm Kench [Red Team] eats Heimerdinger's [Blue Team] turret, which is placed in the bushes in the bottom lane closest to the first Red Team turret. Tahm spits turret out behind him, towards Red turret. regardless of whether turret exits Heimer's active turret range and deactivates or not, the turret enters invincibility phase. Neither I [Jhin], nor Tahm can damage the turret. Red Turret cannot damage it either.
