  Add any missing foreign keys

In the past, some Zanata environments defaulted to MyISAM for new
tables, and so some tables were MyISAM when we tried to create various
foreign keys. (MySQL silently ignores ADD FOREIGN KEY for MyISAM
tables.) This commit ensures that the affected foreign keys are
created if they don't exist.
