Give Genji's double jump the hanzo lunge treatment

[Space-13853]

We’ve also made a change to Hanzo’s lunge ability so if you use it and then wall climb within a tiny window of time, it wont consume the cooldown. This is there to fix a case where you try to climb a wall using the jump button but your lunge ability is off cooldown, which would cause it to be used as you start to climb the wall. This should now be fixed.

Could you do the same for genji? Double jump just gets used on accident many times and this has been an issue ever since double jump reset off of wall was removed(triple jump).
