Migrated TestBoardList from test_board.py to board_test.go

I could not properly check if the test was working as intended because the command `board list --format json` returned an empty list if executed locally.
Further improvements could be done regarding the type of ports, which I suspect should be `map[string][]string` and not simply `[]string`.
