applets/kicker: Fix types on metaobject call to addLauncher
Reason for the change
Some calls via QMetaObject::InvokeMethod()
requires an stricter
type now, instead of the generic QVariant
, because the functions
in task manager's QML code have been type-annotated.
Test plan
Try to pin an item to the task manager using kickoff context menu
Bugs fixed
This fixes the action of pinning an item to the task manager
BUG: 492230
FIXED-IN: 6.2
Note
TIL this happens, but it is something we should be careful of when annotating QML from now on.
For instance, the "Desktop" part still requires a QVariant because it still lacks annotations
