Proper tests for qInfo when it becomes fully available

[nicoddemus]

Followup to #225, qInfo is not currently exposed by the bindings. As suggested in #225 (comment), we can workaround that by using QMessageLogger, but sadly that's not exposed by PySide yet.

For now we can make a simple test for INFO messages, but when QMessageLogger is available (or even better qInfo) we should update the other tests to issue/capture INFO messages.

Closing this as the PR was merged. I also sent a mail to the PyQt mailinglist, so I'd expect it to show up in PyQt soon 😉

Thanks!

FWIW I got the usual "Should be in tonight's snapshot." answer, so qInfo() should be in PyQt 5.11.3, which is planned for after Qt 5.11.2, which in turn is planned the coming week or so 😉
