[GAMEPLAY] Shaco Backstab doesn't modify Statikk's damage

Setup:

• Only Statikk, q leveled up

Expected behavior:

• Backstabbing modifies Statikk's damage by the current backstab modifier

Actual behavior:

• Backstabbing is fully ignored and Statikk only doubles if the hit (backstab or not doesnt matter) is a "normal" crit "as well"
