daemon: Don't leave dangling Action pointers in idle-time containers

If we delete the Action but don't clean up related map/set elements,
the powerdevil daemon can crash e.g. in Core::onResumingFromIdle()
and Core::onKIdleTimeoutReached().

This has been an issue since commit 584cfdf0 (or d91bc62f on 6.1)
which made it possible for already-created actions to get deleted
again at a later time.
Related: bug 490356

Comment 4 Jakob Petsovits 2024-07-22 08:41:25 UTC 
Sorry about the version tag, the fix didn't make it into Plasma 6.1.3 but instead will be in 6.1.4 initially.
