Can't run batch importers in 'create' mode when using multiple lines per item

[Nicklas Nordborg]

That batch importers have support for using multiple lines to import data to a single item. This is for example needed when connecting a child pooled biomaterial with all of it's parent biomaterials, or when adding multiple data files to a raw bioassay.

But this feature doesn't work in 'create' mode. The batch importer will choke as soon as it finds the second line of data for a new item. The stacktrace below is from the test code that has been modified to run the importer in 'create' mode instead of 'create+update' mode.

If the found item is a new item not yet stored in the database the updateMultiLineItem is allowed.
