[GAMEPLAY] Quinn's passive doesn't activate when resetting auto-attack

After using Vault to mark an enemy as Vulnerable, sometimes resetting an auto attack by moving before the attack actually happens (but after hearing the unique passive attack sound) causes the next one or two successive basic attacks to not activate the passive. This causes the Quinn to lose out on the added damage, movement and attack speed of the passive, oftentimes lulling the player into a false sense of security.

To reproduce the issue:

1. Mark an enemy with the passive by using Vault.
2. Once marked, initiate a basic attack but right click to move before the attack actually happens. (note, the passive should still be active after this step and you should hear the enhanced basic attack sound but there should be no real attack)
3. Now, basic attack normally and the passive may or may not activate.

This is a consistency issue with the passive, and this bug popped up somewhere between the last 1-2 patches. This is a critical issue for quinn mains as this can change the outcome of the laning phase or a team fight. Thank you.
