Error when creating new Event through API

[ShaydeNofziger]

The application fails when POSTing a new Event to the API. Preliminary research shows two issues:

• The count comparison is performing explicit comparison between a String and an Int type.
• The Event.forge(...).save(...) code is failing when using Postgres for development.

Steps to reproduce:

1. authenticate as admin or user in professor role.
2. attempt to create a new event by POSTing to /api/event.
3. receive a 400 Bad Request response.

See server console logs for more details.
