Import breaks if there isn't a global request

This is from an add-on with a GS profile which tries to import content. When it is run by plone.app.robotframework's robot server, there is no global request set up.

Traceback:

plone.exportimport could handle this better by getting the request from site.REQUEST

Or maybe we should fix it in plone.app.robotframework

Start with kitconcept/deepl/setuphandlers/initial.py and the import_data path in plone/exportimport/importers/content.py, then reproduce the profile setup through plone.app.robotframework's robot server. Determine how the importer behaves without a global request and verify that the example-content import completes successfully in that context.
