[issue23977] Enhancing IDLE's test_delegator.py unit test

[Al Sweigart]

New submission from Al Sweigart:

As part of trying to understand the IDLE codebase, I'm taking a look at IDLE's unit tests.

-Added more specific messages when test_delegator.py's assertions fail.
-Added detail to the comments.
-Added an explicit test of the resetcache() method (which before was only tested as far as it was called when setdelegate() was called).

I've rerun the unit test on the existing source code and it passes.
