偶尔有 Cannot read 'setContent' of undefined 错误

ngx-umeditor/src/components/umeditor.component.ts

Lines 74 to 93 in 0b08595

	this.zone.runOutsideAngular(() => {
	window.UMEDITOR_CONFIG.UMEDITOR_HOME_URL = this.path;
	let umeditor = UM.getEditor(this.id, Object.assign({
	UMEDITOR_HOME_URL: this.path
	}, this.config, options));
	umeditor.addListener('contentChange', () => {
	this.updateValue(umeditor.getContent());
	});
	this.zone.run(() => {
	this.instance = umeditor;
	});
	});
	// ready 只会在UM首次加载时触发，倒置 [(ngModel)] 失效
	setTimeout(() => {
	this.value && this.instance.setContent(this.value);
	this.onReady.emit(this);
	}, 300);

在大项目中，偶尔莫名其妙出现 Cannot read 'setContent' of undefined 错误。

建议把行90-94，整个 setTimeout 语句移入行 85 this.instance = umeditor; 之后面。
