Comment 1 for bug 1183172

I see several options that can be done

1.
Probably easiest. Cascade delete all summary information about the project, when the project is deleted.

2.
Don't actually delete the project, just mark it with state deleted (advantage here is that the project can be always restored). So the relation between project and summary information will be kept and correct project name will be shown.

3.
Save the actual project name to the summary record (not sure how is that implemented and stored), it can be done upon delete of the project. But this option not seems to be a clean solution.
