Scheduler sometimes fails during slew, moves to next job, or just starts focus

Scheduler sometimes fails during slew, moves to next job, or just starts focus was created by Greg

Running a recent pull from git (maybe a week old) and pretty current indiserver and drivers from git as well on Mint 19. This mount is a Software Bisque Paramount MX+.

I'm having a problem with Ekos where it will fail a job while the mount is still slewing to the target. This *seems* to be more frequent when the job is started with the mount parked but I can't say for certain. Less frequently Ekos will think the slew is done and start the focusing routine. I usually solve the failure by stopping the schedule, resetting the state of the failed job, then starting it again. If there is no subsequent job in the schedule the system will go into shutdown.

Near as I can tell the driver polls the mount asking if the slew is complete and it gets an appropriate response but the driver tries to restart the slew which throws an error. Could be the driver is at fault but I'm not sure. The console logs in Ekos indicate an attempted restart of the slew, which could causing the driver to restart and get the error. Unfortunately I didn't save those logs.

Here's a snippet that I think covers what's going on:

Actually it just failed on the second job after I restarted it. I managed to get the console log this time.
