  grass.jupyter: Test init and session (#2247)

Adds test for Jupyter init, session, and finish using pytest.

Uses temporary script to test automatic (implicit) cleanup with weakref.finalize (always needed).

Uses temporary script for the standard test because the session restores the global state cleanly, namely the global variables in the Python library (temporary solution).
