Apply the metadata changes in id_map to the database synchronously
id_map must be a mapping of ids to Metadata objects. Set any fields you
do not want updated in the Metadata object to null. An easy way to do
that is to create a metadata object as Metadata(_('Unknown')) and then
only set the fields you want changed on this object.
callback can be either None or a function accepting a single argument,
in which case it is called after applying is complete with the list of
changed ids.
