bpo-44955: Always call stopTestRun() for implicitly created TestResult objects (GH-27831) (GH-27882)

Method stopTestRun() is now always called in pair with method startTestRun()
for TestResult objects implicitly created in TestCase.run().
Previously it was not called for test methods and classes decorated with
a skipping decorator.

bpo-44752: Make rlcompleter not call `@property` methods (GH-27401) (#27445)

* rlcompleter was calling these methods to identify whether to add
  parenthesis to the completion, based on if the attribute is callable.
* for property objects, completion with parenthesis are never desirable.
* property methods with print statements behaved very strangely, which
  was especially unfriendly to language newcomers. <tab> could suddenly
  produce output unexpectedly.
