Bid Webfields: Fix conditional text in instructions that appears based on affinityScoreId

[enrubio]

In the paper bid webfields we have this conditional text in the instructions:
${affinityScoreId ? '- Papers are sorted based on keyword similarity with the papers that you provided in the Expertise Selection Interface.' : ''}

However, it seems that we don't create the [role]_affinity_score_id invitations based on whether or not scores are computed. I think this text is always displaying and could be confusing or misleading.
