Master is not reproducible because of LPS-100134

Steps to reproduce:

• Create some tags and categories
• Create some web contents, containing those categories/tags variously
• Put an Asset Publisher on a page, go to its configuration
• Add a category filter, then add a tag filter, Save
• Click on Save again
  Expected behavior: Filter settings stays as they are
