fix: Prevent fallback to existing jobs index

[taratatach]

Backport of #2644

The in-progress jobs query for the export feature relies on the
presence of a very specific index to be fast on cozies with a lot of
io.cozy.jobs documents.

To make sure the index presence detection goes well, we forced a sort
on the worker attribute.
However, since cozy-stack uses an index on worker and state
only, CouchDB fallbacks to this index instead of detecting the index
we want does not exist and runs the slow $or query in-memory.
See apache/couchdb#4511 for more details on
this issue.

To prevent this fallback we will sort on a second attribute not present
in the existing cozy-stack index: message.slug.

### 🐛 Bug Fixes

* Prevent fallback on sub-optimal index for in-progress jobs query.
