Don't double-count institutions in institutionalScoringStrategy

[paulalbert1]

For targetAuthorScore institution match, we should match only from one source: Scopus, if available, and PubMed as a backup. Here, we're counting both Scopus and PubMed as a match.

If there is a POSITIVE_MATCH for Scopus, continue to output the PubMed results, BUT set the PubMed match score to 0.

e.g., ajg9004, 30674375

By all appearances, this is fixed.
