When refreshing Battery Assault with a recast, it does not update the interval of the shrapnels, if the interval reducing talent was chosen in between.

The damage updates immediately, even without recasting (each tick uses current level, not cast level).

Repro:
1. Cast Battery Assault
2. Choose the interval reducing talent on level 25
3. Recast Battery Assault before the previous cast expires

Result: The recast does not update the interval. It continues with the interval from the first cast.

Expected: The buff should update to the current level on refresh.
