Do not calculate aggregates on search UI when no criteria are entered

Doing load testing. In a repository with 100 million documents, displaying the initial search page tajes (with this specific context: high performance Nuxeo/es/mon,go Vas) take ~15s. This is because the 100M docs are returned and aggregates are calculated.
As soon as you filter the search and have less documents, everything is fine (for example, do a fulltext search).

This problem occurs in both JSF and WebUI. Tested on 9.10 SNAPSHOT but it is likely to also occur on 8.10

For content-views (and the corresponding queue in WebUI), a pre-filter may have been defined, so maybe it's only when we know the query will return everything that this "don't calculate aggregates" should apply?
