Reproduction steps:

1. Create a Category in Global scope
2. Create a Web Content with the Category in Liferay Site
3. Export the Site
4. Delete the Category from Global scope
5. Create a Site and import the previously generated LAR file

Result:
The import process finishes.

Expected:
Before the import process starts, the Portal should warn the user that there is a missing reference from the Web Content to the Category

Note:
Master is not affected as the AssetCategoryStagedModelDataHandler class is properly implemented there.
