[FIX] account: reconciliation widget fetch correct reconciliation models

Have a reconciliation model that applies to some particular journals
And that will match some of those journals' lines
The field journal should be filled too
(this field is only the default journal that a proposition will be filled with)

Open the reconciliation widget on a given journal, within the list of
possible journal (from the account dashboard)

Before this commit there was a crashed. This was caused by the fact that
one of the lines that should be displayed had a reconcile model that was not fetched beforehand

After this commit, there is no crash as all relevant reconcile
models are fetched

Note that, on reconcile models, the field journal_id is just there to prefill
the propositions it will create
