Actual behavior

When enabling the python language server instead of the jedi, one looses the functionality to run test on individual methods or functions.

Expected behavior

Run test and debug test functionality remains available when using the python language server

Steps to reproduce:

1. enable "python.jediEnabled": True

2. create a python test file and discover the tests
   one sees the following:
   

3. disable "python.jediEnabled": False

4. reload the window

5. discover the tests
