Adjust identifier registration on object save

Browse Source 
Previously, object identifiers were registered in a commit callback, but that
meant that they wouldn't be available to getLibraryAndKeyFromID/
getIDFromLibraryAndKey within a transaction. Instead, register them before
saving and clear them in a tranasction rollback if necessary.

This changes Zotero.DataObject to call its own _finalizeSave() in addition to a
descendent one.
