Merge both CEP and none-CEP cases into merge functions
Reason to do this:
1. It's difficult to know whether a carrier supports CEP or not without trial.
2. Each current test case of conference call related to call merge has to be divided into 2 cases "CEP" or "no CEP". This makes the customaization of the test campaign trivial.
3. Whether a carrier supports CEP or not can be actually distinguished by proper algorithm automatically, and it does not impact the test result, either.
