fix: flag API positional arguments

To reproduce the error:
- switch to mongodb from mysql for a specific course.
- create a thread and report the thread. It'll throw an error due to wrong positioning of the arguments.

So, this commit
- uses keyword arguments in flag APIs
- adds mock tests for code coverage
