Commit message

Query: allow adding more than one result for each doc, allowing indexing subfields of objects in a list

This is to be conformant to what the u1db specs (implemented in python) say.

Description of the change

Indexing subfields of ojects in a list doesn't work as expected in u1db-qt, we only list the first element and not everyone as defined in docs [1].

The reason was that we didn't add a result if we already had one for that doc... And this seems wrong to me.

In a next MP we should probably also fix the "Name a list" case (see [1] again).
As test-case you can also try [2].

This turns out to be a surprising explanation to the related bug. This makes sense.

I might feel that a QML unit test is potentially simpler, but no strong feelings.
