It's possible for a Comment to have both issue_opened=False and

issue_status=OPEN. We weren't checking for this during counter

initialization, resulting in such comments being included in the count.
The reason why they end up in this state is a separate issue that should

be addressed, but it's certainly easy to work around. We now properly

check the issue_opened field before even considering its issue_status.
There's also a fix for transitioning an issue status when saving the

Comment when issue_opened is False. This is needed for tests, primarily,

but would probably also solve some issues that could come up in the API.

The unit tests failed with the reported error conditions without the

fixes to the counter initialization. After the fix, the tests all passed.
