AttributeError on relative import

It appears that a relative import breaks test discovery during assertion rewrite. The error is:

_pytest\assertion\rewrite.py:113: in run
>                 item.identifier != "__future__"):
E   AttributeError: 'ImportFrom' object has no attribute 'identifier'

I'm attaching a package which if tested under 2.1.0.dev4 reports an error but under 2.0.3 completes the test naturally.
