ownCloudProv : remove trails
Trash: load trash bin at startup. Use biji_manager_get_items

We should not parse Trash folder everytime trash bin is visited. Load at startup and follow-up note beeing trashed. Some work needed on this.
localNote: update "location" when note is trashed

So we can restore it without first closing application...
selection: go back to normal mode once item restored or deleted

This was already done on classic view but not for trash bin actions.
Restore : add a signal for the sake of controller
restore: makes the note back into notes

When an item is restored, keep track of it.
Add an oldUuid string to ::restored signal so
manager can remove item from trashed table.
