add more tests, improve tests, fix tests

The number of tests should probably be increased, and each test should cover all possible use cases of each commands. Certain existing tests might contain useless lines or need to check more use cases.

A little work has been done on this subject. More of both streamlining and beefing of tests is soon to come.

The end result should be an entire suite of tests able to demonstrate the accuracy of all deterministic commands. So far mostly the original core commands are tested and not all forms of similar name matching is demonstrated in testing. Both the world and the tests need to be updated to handle this.
