Git commit 8e8ef50b9faa3c2365dcf60f9d8dac71c55c0440 by ivan tkachenko.
Committed on 23/04/2024 at 18:18.
Pushed by ratijas into branch 'master'.

Fix connection lifetime issue

The lack of receiver may cause undefined behavior / segmentation fault
crash if, for example, a KActionCollection is stored as a
Q_GLOBAL_STATIC too and coincidentally gets destructed after the
KGlobalAccel singleton instance.

Note that all other connections in this file use this `q->connect` style
and already have a context object set to `q`.

Test case: Run `plasmoidviewer -a org.kde.plasma.clipboard`. With this
patch is still crashes on exit, but now in a different place.
