Re-open library when clicking it in side bar
requested to merge 494-clicking-on-a-library-tag-in-the-sidebar-should-always-clear-the-stack-and-open-that-item into development
This fixes a bug (or strange behaviour) that, when clicking again on a library which was open e.g. before opening the settings, this had no effect. This is improved now, so when we click an entry, we always reset the stack (so this can be used to go back to the library root when currently viewing e.g. an item further down.
Closes #494 (closed)
