`EventSourced` actors failed to clean up its timer on death

[Arkatufus]

Version Information
Version of Akka.NET? dev
Which Akka.NET Modules? Akka.Persistence

Describe the bug

The timer in question is in this line:

akka.net/src/core/Akka.Persistence/Eventsourced.Recovery.cs

Line 185 in 5161195

var timeoutCancelable = Context.System.Scheduler.ScheduleTellRepeatedlyCancelable(timeout, timeout, Self, new RecoveryTick(false), Self);

If the actor is forcefully killed while inside this state, it fails to call timeoutCancelable.Cancel() and will cause infinite RecoveryTick messages to be dead-lettered until the actor system is restarted.
