V10 support - Can no longer select default token in v10

[Almarane]

Hello there

Had to update to Foundry v10 to have my systems working again. I tried reusing TokenHUDWildcard, but I can no longer select the default token from the prototype token of my characters.

I can still change the displayed token from right-clicking the token, but now when I drag'n'drop a character with a wildcard token it just acts like a regular wildcard token, choosing between the images at random.

Fixed this in my fork as a temporary workaround, see #33 (comment)
