* 使用过程中发现的两个低级错误

laya.spine.js:
SpineTemplet_3_x 和SpineTemplet_4_0 这两个类的loop方法里有一些问题，assetManager的错误检测应为放在完成检测之前吧，这样会导致真的发生了加载错误，因为parseSpineAni会报错，导致ERROR事件也抛不出去。

private loop() {
		if (this.assetManager.isLoadingComplete()) {
			this.parseSpineAni();
			return;
		}
		if (this.assetManager.hasErrors()) {
			this.event(Event.ERROR, "load failed:" + this.assetManager.getErrors());
			return;
		}
		Laya.timer.frameOnce(1, this, this.loop);
	}

spine-core-3.7.js问题：
代理里有语法错误，state !== status

[code] }, (state, responseText) => {

                this.errors[path] = `Couldn't load texture atlas ${path}: status ${status}, ${responseText}`;
                if (error)
                    error(path, `Couldn't load texture atlas ${path}: status ${status}, ${responseText}`);
                this.toLoad--;
                this.loaded++;
            });[/code]
