AttributeError: 'Tag' object has no attribute 'gramps_id'

A Tag is a TableObject rather than a PrimaryObject so it doesn't have a gramps_id.

Right, but I believe there error is in Gramps core:
https://github.com/gramps-project/gramps/blob/master/gramps/plugins/tool/check.py#L1416

It assumes a referenced object is a primary object, but it can be a tag as well.
