BDK Death Strike Minimum Heal Too High

[serrapaladin]

Describe the bug
Blood DK's Death Strike is falsely adding the modifier from Improve Death Strike onto Death Strikes that heal the minimum of 7% of max HP. This makes the minimum value it heals for about 45% too high.

To Reproduce
Steps to reproduce the behavior:

1. In the Blood DK sim, make any encounter with 0 DTPS, for example Encounter = Default/Raid Target, Tank Assignment = None
2. Run the sim with the standard Blood Spec.
3. Remove the 3 points in Improved Death Strike and rerun.
4. Compare healing done per Death Strike.

Expected behavior
In-game, it looks like the logic is: calculate DS heal including all modifiers, and if the final result is less than 7% max HP, set it to 7% max HP. That final healing amount should just be 7% of max HP, not further modified by Improved Death Strike.
