JSON field Error when Importing Temporary Layer that was previously a Temporary Layer

[KellyMWhitehead]

@KellyMWhitehead This is the current error CRITICAL Feature Class copy exception: Object of type QVariant is not JSON serializable.

This has happened on other layers as well. Issue goes away when deleting fields in temporary layer. I think the metadata json field might be the issue from the temporary layer if that layer originated from the project.

I am unable to reproduce, even with a metadata field - this is a useful but non-critical workflow, lets dig in for a fix in 1.1.

@KellyMWhitehead I also cant reproduce. I'll leave open for now and remove the milestone 1.1. If it happens again Ill thoroughly document it and zip up the project.
