Bugfixing for /user endpoint.

[jason-fox]

• Add null check
• Remove IS operator
• Add SQL hardening

Proposed changes

540c3e5bd5 adds an IS operator to trusted applications. When firing the PDP with the /user end point, with MySQL 8, this results in the following Sequelize error message:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near'

Fix is to remove the Op.IS operator since the SQL is not checking app_id IS NULL or the invalid app_id IS 'xxxxxx', but should be checking app_id = 'xxxxxx'

Also on oauth2.js, the JWT check assumes that the database holds token_types and if it is null, the app errors with Cannot read property 'includes' of undefined
