LPS-36109 - Duplicated "Load more results" link in asset category selector

Hey @marclundgren,

Attached is an update for http://issues.liferay.com/browse/LPS-36109.

NOTE: The service call to return just that child's node count is:

Liferay.Service(
	{
		'$categoriesCount = /assetcategory/get-subcategories-count': {
			'groupId': themeDisplay.getScopeGroupId(),
			'parentcategory': '[currentItem]......categoryId'
		}
	}
);

Please let me know if you have any questions.  Thanks!
