[Bug]: NPE when onCampaignLoad creates Lib:Token

[Jmr3366]

Describe the Bug

When you create a library token through onCampaignLoad, you can produce the attached NPE error on the server when the player connects for the first time. Subsequent reconnects do not produce the error. To reproduce a second time you have to delete the Lib:token that was created, and close the MapTool server session, open MapTool, load the campaign, start server, issue should repeat

To Reproduce

On an existing Library token, create an onCampaignLoad macro.
This code:

[h: tokenImage = getTokenImage("",findToken(getMacroLocation()))]
[h: tokenTemplate = json.set("{}", 
	"name", tokenName,
	"tokenImage", tokenImage,
	"size","medium",
	"layer","token",
	"gmName","",
	"relativeto", "map",
	"x", 0,
	"y", 0
)]
[h: tokenID = createToken(tokenTemplate)]

Expected Behaviour

A meaningful error if it is a real failure or "" if it's a false/positive

If true/positive I'd expect it to be somehow mitigated (not exactly sure how yet though)
