[FIXED] [Paladin][Protection] Avenger shield silence

[FreakzStaff]

Description of the bug
----------------
https://www.wow-freakz.com/spells.php?spell=231665 (wowhead link) silence effect is capped to one target. You can't have the silence effect from avengers shield on multiple enemies.

How to reproduce
----------------
Cast multiple avengers shield on different targets. You'll see that the silence effect is removed from the previous target and applied to new one. You can even try with divine toll and you'll see it'll only silence one target.

How it should be
----------------
The silence effect should not have any target cap, meaning you can apply it to different targets at once. A good synergy with divine toll where you can silence for 4s an entire pack of mobs.
