Videos / Search: facets not reset by new query

[costaflavio]

Expected behavior

The query should reset the faceting (search query is "hierarchically superior" to the faceting, or faceting applies to search results)

Actual behavior

When entering a new query after faceting the previous query, the old faceting applies to the new query.

Information about the Issue

videos.cern.ch on 2018.06.20 with Chrome 67

Steps to reproduce the behavior

1. For example, run a search on all Videos
2. with the full list, facet them (e.g. restrict years up to 1996)
3. in the search box type any query, e.g. title.title:"foo bar"
4. check the message that appears
