Submitted with commit 49a1a2827639b3099a2f16fc3c8eef6130e4d95d by Marco \
Martin to branch master.

Description
-------
Fixed version of /r/123350/
Why VisualDelegateModel? It may be workaround/hack/you name it but it was \
the only way I found acceptable. You need to pass QModelIndex to openItem \
and I don't know how to get it using plain ListView and SystemModel. \
VisualDelegateModel has a convenience method modelIndex which is already \
used in KickoffItem.qml (but only if ApplicationsView tab is active). I \
changed BaseView to use VisualDelegateModel to have modelIndex method and \
to be more consistent with ApplicaitonView.
"this change seems uneeded; we're using modelIndex fine in the old code, \
see line 40 in KickoffItem.qml in the old code. (unless maybe that didn't \
work ?) My understanding is setting the model to a QAIM, internally just \
creates a VDM anyway."
It didn't work. modelIndex is used only if flag hasModelChildren is set to \
true. That can happen only for ApplicationView, as only there children \
exist. Also ApplicationView uses VisualDataModel explicitly, so method \
modelIndex is available. In SystemView model is set directly, \
VisualDataModel is not created implicitly (or even if it is it is not \
accessible). In other words listItem.ListView.view.model returns \
SystemModel object which is QAbstractProxyModel/QAbstractItemModel \
implementation. SystemModel does not have any slot that would be usefull in \
this case. Passing "model" variable is not an option. It would be a good \
idea as it contains all data related to current item but this is internal \
QML/Qt Quick class.
In KDE 4 it was not a problem as it was easy to get QModelIndex from event \
(lines 860 - 878): https://projects.kde.org/projects/kde/kde-workspace/repository/entry/plasma/desktop/applets/kickoff/ui/launcher.cpp?rev=KDE%2F4.9

Testing
-------
I was able to reproduce bug using latest GIT code.
Screenshots, first shows not mounted removable device, second is error \
message (in Polish): \
https://www.dropbox.com/s/8vcokx17kmn3onw/zrzut%20ekranu1.png?dl=0&s=sl \
https://www.dropbox.com/s/sqkci1z1fhb3h3p/zrzut%20ekranu2.png?dl=0&s=sl
In console I can find this message:
Opening item with URL ""
It looks that KFilePlacesModel->url(index) returns empty string for not \
mounted devices. I have 5.9.0 version of libkf5kiocore5 installed.
Patch fixed mounting. I also tested all tabs, all items works as expected.
