The labels on the discovery page display the authority id instead of their label

[alexandrevryghem]

Describe the bug Currently the search labels are created based on the filters & their values present in the url, instead of using the appliedFilters that is sent back from the backend.

To Reproduce Steps to reproduce the behavior:

1. Enable authority for the author field
2. Make new item submissions for that author
3. Go to the search page and select the authority value from the author facet
4. The label displays the authorityKey instead of the display value

Expected behavior The label should be used instead
