Description

Previously, when assertWarnings() found fewer or more warnings than
expected, the only result we'd get was an assertion error showing the
mismatched lengths.

Now, any mismatches between expected and actual warnings will result in
a full list of the mismatches, helping with diagnosing which warnings
were missing or added.

Testing Done

Unit tests pass.

Tested this with an assertion error I hit. Verified I got a more useful
warnings display.
