#14542 Summary: Assign unique case ids when importing multiple cases

Summary cases are created and given a case id before they are added to the
project. The id search only sees cases already in the project, so every case
in a batch import was given the same id.

The Data Sources tree stores the owning case id in each summary address, and
all lookups resolve to the first case with that id. Selecting the same vector
from several cases therefore produced a single curve, and dropping a vector
from one of the other cases hit the duplicate check and did nothing.
