This modifies the places where output_get_active_workspace is called to handle a NULL result. Some places already handled it and did not need a change, some just have guard off code blocks, others return errors, and some have sway_asserts since the case should never happen. A lot of this is probably just safety precautions since they probably will never be called when `output_get_active_workspace` is not fully configured with a workspace.
