[Bug] Launchers not using new kill date

Bug

When generating a second launcher of any type the kill date of the new launcher is not used. If the original kill date has passed all new Grunts from the new launcher will still auto kill when they connect.

**To Reproduce**
Steps to reproduce the behavior:
1. Generate a PowerShell Launcher with kill date 1
2. Change kill date to a later date (kill date 2)
3. Click Generate
4. If kill date 1 has passed all new Grunts will automatically disconnect when activated.

**Expected behavior**
The new kill date should be applied to all future launchers generated.
