Duplicated object key declaration in app.vue

[t-heuser]

Hi!

Was wandering through the source code and found a duplicated object key declaration. Nothing wild, but can be safely removed I guess.

'node_template': null is duplicated in lines 122 and 125.

magento2-menu/view/adminhtml/web/vue/app.vue

Lines 116 to 129 in e953c98

	addNode: function(target) {
	target.push({
	'type': 'category',
	'title': this.config.translation.addNode,
	'id': uuid(),
	'content': null,
	'node_template': null,
	'image': this.selectedItem.image,
	'image_alt_text': this.selectedItem.image_alt_text,
	'node_template': null,
	'submenu_template': null,
	'columns': [],
	'is_active': 0
	});
