Import breaks if there isn't a global request

[davisagli]

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:

TypeError: 'NoneType' object does not support item assignment

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

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