[Bug]: getAllPropertyNames error on type not present

[bubblobill]

Describe the Bug

getAllPropertyNames(type, delim) creates an error causing macros to stop running where the type does not exist in the Camapaign Properties.

To Reproduce

1. Copy the following -> [r: getAllPropertyNames("Franco_Prussian_Soldier_Specialist_Artillerest_16thCentury", "json")]
2. Paste into chat, press Enter.
3. Read the error message.

Expected Behaviour

I would expect it to return an empty set or false.
Without being able to determine what token types exist within the campaign there is no way to know if the function is safe to call.
Accordingly I would expect it to return something useful that can be handled in code if the type is not present.

It is not clear to me if this should be closed from #3548
#4697 could also mitigate the issue (by checking first)

Haven't tested it but it appears closable.
