Unit-tests need to be rewritten

[RavenX8]

We need to rewrite some of the unit tests, mainly the ones that test server functionality. We should create mocked classes that way we can truly verify that things are working as intended. We should actually move each test area into their own executable that way we can actually make use of the mock classes.
