Fix single runner mode
We have to pass the m_runner parameter to the runner manager, otherwise it defaults to an empty string.
The m_runner is already correctly set when we activate the single runner mode using dbus. See https://invent.kde.org/plasma/plasma-workspace/-/blob/master/krunner/view.cpp#L304
Test Plan:
With the following command only bookmarks will be displayed.
qdbus org.kde.krunner /App org.kde.krunner.App.displaySingleRunner bookmarks
After that launching KRunner with the normal shortcut will go to the normal search mode.
Same for a dbus activation, for example using:
qdbus org.kde.krunner /App org.kde.krunner.App.display
