[FIXED] [Mage][Arcane] activating Arcane Missiles!

WoW Freakz spell link: https://www.wow-freakz.com/spells.php?spell=79683&&name=arcane-missiles
Bug description: Right now spells activate Arcane Missiles! when they hit the target (behaviour from MoP), but they should activate it as the cast is finished, as stated in Arcane Missiles tooltip: Each damaging spell cast has a x%...
Proof:
Arcane Barrage activates AM when cast and not when the target is hit

This bug makes difference in gameplay for some spells:

1. Spells that deal damage at the end of cast = no travel time+initial hit
-Arcane Blast - parts of a second difference
-Supernova talent- parts of a second difference
-Nether Tempest talent(initial hit+dot) - parts of a second difference
-Arcane Explosion- big difference,you should be able to activate AM even if you don't hit a target

2. Spells with no travel time+ delayed dmg
- Mark of Aluneth- a little difference, right now AM can activate at the first thick of dmg; should be after the cast

3. Traveling spells
- Arcane Barrage - big difference, right now AM can activate when barrage hit the target; should be after the cast as in the video above


-Arcane Orb- big difference, activates AM when it hits a target; should be after the cast,
*Also another bug: it can generate more than one AM stack when it hits a lot of enemies; (maybe related to the Arcane Charge generation?? which is working fine)
