fsm_test: more thoroughly test FSM inst ids and names

Place id and name testing in its separate section, test_id_api().

Add a test that actually allocates an FSM instance with a NULL id, which is
allowed, but uncovers a bug of an unset FSM instance name. osmo_fsm_inst_name()
falls back to the fsm struct's name on NULL, but osmo_fsm_inst_find_by_name()
fails to match if the instance's name is NULL (and until recently even
crashed). Show this in fsm_test.c with loud comments.

Add test to clear the id by passing NULL.

Add test for setting an empty id.

Add test for setting an invalid identifier (osmo_identifier_valid() == false).
