Subject: [PATCH] fix(api): replace the build of the ids of documents by a
 single SQL query.

This increases the performance of `/api/documents/` up to 60% on a ~1400 documents database (~600 ms > ~240 ms on laptop). This optimization only applies to the basic "list documents case", not the "search case".
