Fix summaries generation for anonymous classes

[Markoutte]

Description

Fixes #2458

Anonymous classes have no canonical name. Summaries fails to find those names and no test can be generated because of this. I've changed the call from canonicalName to name that (I think) is the same in the most situations.

How to test

Manual tests

Run ContestEstimator from the origin issue. It should generate test as expected.
