Fix service comparison when starting a stopped service

Browse Source 
When comparing a stopped container after a start request, the container
ID will be present in the target state (where usually it is not). We
were already filtering this value out of the current state, but
neglected to do so for the target state. This change now ensures we
remove it from both alias lists if it exists.
