WIP: tests: remove gmm unit tests
The TTCN3 tests should replace all of the GMM unit tests.
The GMM unit tests uses send/recieve LLME while TTCN3 is using BSSGP
tx/rx to the same.
TTCN3 has better tooling and can handle packets more easier.
The unittests expect the package in a specific order and do checks
the internal state, which is now changing because of the new FSM.
TODO: compare TTCN3 <> unit tests and add missing checks.
