Kstars crashes

[Eric Dejouhanet]

For what it is worth, I found the issue I was describing. When using
PHD2, the Ekos Guide module reacts to star-lost events by issuing a
new capture, which conflicts with PHD2 activity.

In my case, PHD2 is using subframes, so Guide unexpectedly receives a
small frame, but does not react, which triggers the capture timeout
event, which removes the CCD driver and reconnects it.

In my case again, both CCD are managed by the Atik driver. Thus, PHD2
dies when the guiding camera driver disappears, and Ekos dies when
Scheduler restarts capturing on the main camera.

I'll be issuing a MR to fix that mess.

Without any particular reason, at some point in the middle of repeated guiding/image captures with two Atik cameras, Ekos will suddenly log "Removing managed driver..." and kill the dual Atik driver before restarting it. Then Ekos crashes on the next interaction with any CCD, due to signals going to deleted objects. It seems that subsequent problem is in baseclient, but I need to find out the reason of the preliminary disconnection.
