[SWADE] Ctrl+Z breaks connection between Combat Tracker and Token

[FrodoB]

Hello,

as discussed on Discord, there seems to be a problem with Ctrl+Z as it relates to the combat tracker.
Steps to reproduce:

1. Create a new SWADE campaign, just to make sure this is an issue with the core ruleset.
2. Load an image and add a grid. I used "Red's Band", but any image should be okay.
3. Add two NPCs to the CT. I used Bear and Alligator/Crocodile, but any two NPCs should work.
4. Drag the NPCs from the CT to the map.
5. Drag an attack of NPC#1 directly onto the token of NPC#2. As expected, an attack is performed.
6. Move NPC#2 and then undo the move with Ctrl+Z. This is where it breaks.
7. Drag an attack of NPC#1 directly onto the token of NPC#2. Nothing happens.
8. Remove the "broken" Token and re-add NPC#2. The re-added token works as intended again.

Cheers

Here's an easier set of steps to repro:

1) Add PC to map. Note Green friendly token background denoting that it's attached to the combat tracker.
2) Move PC.
3) Hit Ctrl+Z.
4) Note that Green friendly token background is no longer present, and it's no longer attached to the PC in the combat tracker.
