Correct two straggling "%Q" + "implode(...)" callsites in Revision updates

Summary:
See <https://discourse.phabricator-community.org/t/error-seems-to-be-related-with-da40f8074-and-php-7-3/2102/12>. When creating or updating revisions, we do some manual query construction to update the affected path table.

Update these queries to modern `qsprintf()`.

Test Plan: Created and updated revisions affecting paths, no more logs in the webserver log.
