Switch myisam to innodb for fulltext_record_properties

Reopening this one against the release branch.

This change was made because fulltext record properties table crashed on grc-dev and grc-test. The issue was resolved with REPAIR TABLE clause. Running the reindex script did not help.

Based on https://cloud.google.com/sql/faq#innodb myisam should only be used for full text search, but we aren't using full text search anymore.
