After applying filters on Studies page nothing happens

[Constantine Rafikov]

When applying filters a new query should be made and search feed should be updated instantly. But after applying filters nothing happens. Filters only being add to query as the parms only when user makes new search.

1. Compile frontend bundle or go to production, go to/experiments section
2. Open Network tab of Chrome
3. Choose any variant in any filter select
4. Notice there is no new api/research/** query Network
5. Now type in something in the search field and press enter or tap search button
6. Notice a new api/research/** query Network

Expected behavior

When applying filters a new query should be made and search feed should be updated instantly.

Actual behavior

After applying filters nothing happens (no query, no search feed update).
