h1brsey autostarts, h1brsex does not

WP 6164

When h1brsex reboots, it appears that the C# code starts before the PLC and therefore fails. This does not appear to be case for h1brsey. I have taken out the automatic starting of the C# code and EPICS IOC at h1brsex. I have left the PLC to automatically restart.

I restarted h1brsey twice to check that it had not worked by random coincidence, and it worked both times. I restarted h1brsex more than once and each time it failed.

According to the documentation the C# code should be starting after the PLC.
