This uses [teyit](https://pypi.org/project/teyit/) to modernize asserts,
as recommended by the [unittest release
notes](https://docs.python.org/3.12/whatsnew/3.12.html#id3).
For example, `assertTrue(a == b)` is replaced with `assertEqual(a, b)`.
This produces better error messages, e.g. `error: unexpectedly found 1
and 2 to be different` instead of `error: False`.
This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

We were checking "WasTheLastResumeForUserExpression" but that returns true even
if that expression was completed, provided we haven't run again. This uses a
better check.
This is actually fairly hard to trigger. It happens the first time you hit an
objc_exception_throw breakpoint and invoke that frame recognizer for that. But
I couldn't trigger it using a Python based frame recognizer. So I wrote a test
for the objc_exception_throw_breakpoint recognizer which should have been there
anyway... It fails (the target auto-continues) w/o this patch and succeeds with
it.
