Fix user e2e tests (#194)

* WIP fix user e2e tests

The e2e tests still don't seem to work due to migrations not running.

Changes:
- update user.e2e tests to use new `userService.createUser` method
- fix server `typeorm` command to use ORM config
- update make test-e2e to re-create database volume every time
- add User DTO
- update auth.service and user.service to use User DTO
- update CreateUserDto making optional properties that are optional

* Fix migrations
- add missing `.ts` extension to migrations path
- update user e2e test for the new returned User resource
