fix record default value cannot be a collection/map of records

[ex-ratt]

This fixes #592

(Is there anything else I need to add? Seems like a small enough change that it doesn't need additional explanation, or does it?)

I changed the line that had the issue, hopefully it'll work now. I enabled Github actions in my fork, but it does not work, because my fork does not have any tags (line 294 in build.sbt will fail if this is the case). But here it may work, fingers crossed. If not, then I will try again.

PS: I force-pushed in order to prevent a confusing history of small fixes. Is this ok?

Thanks for the fix 👍
