LPS-50178 Multi scope Asset Publisher does not work with tag filtering

Hey Julio,

I have fixed this issue some time ago and delivered in a hotfix already because by the time it was created it could not be tested on master due to a regression, but it can be now so I'm sending this pull.

Please check the use cases I have put together to make sure it behaves correctly now: https://issues.liferay.com/browse/LPS-50178?focusedCommentId=539547&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-539547

Thanks,
Ákos
