Refactor/Optimalisation Filters config

[maria-j-k]

Currently opening search service triggers get function in FiltersConfigsRepository 1000 times. The function is called not only for the collection from url, but for each available collection.

https://github.com/cyfronet-fid/eosc-search-service/blob/development/ui/apps/ui/src/app/collections/repositories/filters-configs.repository.ts

• [ ] filters config should be called only for selected collection
• [ ] filters config should be called only once at one request.
