https://git.reviewboard.kde.org/r/126459/ introduced new flag that allows to skip the grouping of notifications. This should fix all bugs caused by checking for appName being "plasma_workspace" which are all default notifications from any plasmoid. CCBUG: 356653 REVIEW: 126461 (this also needs to raise the KF5 dep to 5.18 which is normally done at release time, but in order to use this now, it needs to be bumped now, otherwise build failures will ensue)
