Title: Reset the paper review stats when removing it

- reset the review state of a paper within a contribution if the paper is
deleted
- allows to reupload a paper if the contrib's paper is removed while awaiting
review
- enable the `Upload paper` link in the "Material to Review" tab of the
contrib's management area if there is no paper submitted
