test_Globals should be converted into two separate fixtures

[ghost]

Actual approach - makro - doesn't fulfill to well its task. Also two fixtures should be more flexible tool.

Can you give more specifics about this issue? Do you mean #355 ?
I have refactored test_Globals in my proposed branch in that issue.

Partially, it fixes mess caused by makro, but there's is still that connected with constructing world.

Problem:
There's is a lot lines of code like:

openrw/tests/test_GameWorld.cpp

Line 22 in a0b97a4

gw.state = new GameState();

You need to build world on your self, know structure of it, remember to cleanup. It adds many unneeded lines of code. Prevent fixing leaks (without using shared_ptrs).

Fixing that can be done, by preparing two separate fixtures (with data and without) which are able to construct as simple as possible, but working world(s).
