top containers migrated from locations may lack type information

For ALA and UA, boxes are typically listed by numbers only, not with label (e.g. "Box"). However, in ASpace it would make more sense if these were assigned the "box" label. It may be worth considering whether to set "Box" as the default label if there is none found in the "content" field for the location information.
