Fix incorrect view selection in LogbookWidget

Closes #100 - the problem was caused by using a QHash instead of a QMap where ordering mattered.

From the [docs](https://doc.qt.io/qt-5/qhash.html#details): QHash is unordered, so an iterator's sequence cannot be assumed to be predictable. If ordering by key is required, use a QMap.
