Wikidata.reconcile progress message - say how many QIDs were fetched

[Dominic-DallOsto]

#38 enables batch fetching of item or citation QIDs. When batch fetching, the default behaviour is to only accept the QIDs of any items for which there is an unambiguous match. When fetching a single QID, a popup menu shows the possible matches if there are multiple and provides the option to create a new Wikidata item if there are none. In comparison, batch fetching QIDs doesn't provide much user feedback.

It might therefore be nice for the Wikidata.reconcile method's done progress message to read something like "XX QIDs fetched" if more than one item is provided for reconciliation. In this way, users would know whether they needed to go back and fetch citations for items one by one.

Thank you, Dominic.

Might be related to #90.

We could have it read "QIDs fetched for XX items" instead of "XX QIDs fetched", so it would be compatible with running reconciliation for several items with approximate matches enabled.
